Scots college involves Kerfoot replacing the main switch board for the school as the existing switchboard has rusted through.
The new main switch board supplied by Kerfoot a stainless steel powder coated white with Galvanic Corrosion isolation barrier. The switch board will be fitted out with new control gear, circuit breakers and meters.
The works to follow consists of the following
The requires Kerfoot to disconnect the main supply to school down from the substation.
Kerfoot will then proceed to disconnect the existing electrical feed and remove the cabling out of the switchboard.
Once the board and cabling is disconnected a crane is required to pull the old board out and install the new board into position.
The new switchboard will then be secured ready for cable to be re- installed
The cabling will then be installed and re-lugged and installed secure into position.
Once the terminations have been completed, Kerfoot will conduct a testing.
Ausgrid will then will turn the power back on and Kerfoot will continue with testing.
Kerfoot completed the full upgrade of all lighting in the Ku-Ring-Gai Council’s main administrative building (5 story building).
All Lighting was replaced with LED. PE cells, light censors and occupancy sensors were also installed to reduce the times when lights are left on when areas are not being used.
The project hopes to reduce the total energy use for lighting in that building by more than 50% of current use.
We worked closely with council to determine the best solution to each area keeping in mind the ROI target of 18months as a maximum set by the council.
Located in the heart of Sydney’s Northern Beaches the newly completed Pittwater private Hospital is a purpose built 85 bed private hospital delivering a range of exceptional healthcare services within a hotel style environment.
The hospital would provide short and long stay accommodation for patients recovering from surgery and medical conditions and would provide medical rehabilitation and palliative care.
The hospital also has three surgery theatres, hydrotherapy, physiotherapy, treatment, conference and consulting rooms.
Kerfoot where engaged on this project to complete the Mechanical Electrical scope of works and where heavily involved in the design of the Mechanical Systems.
This consisted of the following:
Design and manufacture of three new Mechanical Switchboards both Essential on Non-Essential
The Essential Services scope of works consists of Stair Pressurisation, Smoke exhaust and Motorised Fire Damper Actuators to control and contain smoke in the event of a fire.
The Non-essential scope of works consists of complete VRF air-conditioning system within the bedrooms and common areas controlled via a Central Controller with BMS monitoring capabilities. It also consisted of mechanical ventilation to each of the bedrooms and common areas (HVAC). There is also a Pool Plantroom designed to maintain pre-determined humidity and temperature set points all year around.

At Kerfoot, we are specialists in lighting automation. If you own or operate a business in a commercial space, we highly recommend investing in a custom design system for your building.
There are a number of great benefits that will accompany the installation and operation of your new lighting system. The main advantage of an automated lighting control system is the user’s ability to manage an entire network of lights with one controller. You will be able to create dynamic and complex lighting designs thanks to this comprehensive level of control.
Take a look at the following range of additional benefits a new lighting system could bring to your business. If you have any questions, get in touch with us today for a consultation.
Energy Efficiency
Our automated lighting control systems are energy efficient, thanks to timeclock, motion sensors, and PE Cells. These factors also contribute to practicality.
Conditional Settings
Automated systems have an extensive range of options and settings that you can configure based on a number of factors. You can choose to adjust the light levels according to the light levels outside or choose a system with occupancy sensors that turn off the lights when a room isn’t in use. You can even integrate your lighting control system with your emergency alarm system and change the lighting conditions for emergency conditions.
Flexible Installation & Integration
We can easily integrate your new system with your existing technology – whether it’s an emergency alarm system, a CCTV system, or an existing lighting installation, we can design a solution that fits your needs. Automated lighting systems are really flexible in their design options. The sensors, switches, and lamps don’t have fixed positions – this means that you can get a lighting design that is optimised for your unique environment.
Low Maintenance
Once you have chosen an automated program that meets your needs, you can let it run independently. The automatic nature of our designs allows business owners and managers to focus on the job at hand while the lighting is taken care of.
Portable Control
Thanks to advances in technology, you can control your lighting systems with mobile apps, tablets, and laptops. If your building has an automated system that is shared with multiple commercial tenants, each user can control their section with an app on their phone (or another device). This will allow you to avoid conflicts with other building occupants and control your area in a way that suits you best.
Choose Kerfoot for your Automated Lighting Control Requirements
We work with local lighting automation manufacturers to ensure that our clients have access to the latest and greatest advances in the industry. We can supply and install a custom design in your commercial or industrial space.

Kerfoot Projects was awarded the electrical services and were very excited to be a part of this project. This Project is one of the first where LHD and Sydney UNI are incorporated as one to creating a learn space.
This fit out/ Refurbishment consisted of the following spaces
Large Formal Teaching Rooms
Informal Teaching Spaces
Collaborative Theatre
Cabaret Theatre
Seminar Rooms
Meeting Rooms
LHD Staff Room
Comms Room
Accessible WC
The project included the supply and installation of
Power
Lighting
Monitored Emergency Lighting
Dynalite Lighting Control
New Communication Room
Communications Cabling including Fibre Optics, Copper ties from the main frames & CAT6A cabling
New switch Boards plus new sub main cabling
This Project took a lot of planning as we were required to provide minimal disruption to the hospital, patients and other facilities. The supply and Installation of the new sub main cabling from the sub-station took nearly 2 months of planning to organise a shutdown to connect into the sub-station as we were required to identify all affected areas and required to supply temporary power and lighting to critical affect areas
Not only with the hospital being operational 24/7 also the unique design of this refurbishment took a lot of coordination to ensure everything could be installed correctly and operational for its purpose.
Now open the WECC is open is a hit with the public as you can see the facility from the cafeteria and the feature lighting has been a huge hit with all parties.
Kerfoot management are very proud of this project and the team that helped competed it.

Project Description:
The project presented a major logistical operation to manage, identify, disconnect and remove the existing services & infrastructure simultaneously undertaking the installation and connection of temporary supplies, implementing new services without effecting security or daily operations of the ATO.
Kerfoot was presented with a significant challenge; to replace the existing Main switchboard and site power Distribution system without any downtime to the ATO. Kerfoot successfully executed a faultless shutdown & changeover in just one weekend returning power to the site earlier than projected.
The preparation, staging and installation practices Kerfoot implemented on this project were meticulous and was 6 months in the planning resulted in a seamless transition without affecting the ATO business The Client was extremely gratified.
The amount of planning, co-ordination and problem solving required to deliver the amount of services adjustment through a trading building has refined our skills and showcases the attention to detail we can provide.
Kerfoot was engaged after the successful completion of the main buildings works, NDIA moved in to Ground floor and level 2.
The project consisted of the fitout to the Ground floor and part level 2 in the ATO building. The Base building infrastructure was re-used where possible and new services installed as required to provide the new documented layout.
The existing power Distribution system was modified to accommodate the new design. The Tenant DB`s have a non-essential and essential (generator backed) section and the fridges, Security and communications equipment is connected to the essential section. The balance of the power services and connected to the non-essential section. The power subcircuits were all new and installed through the existing ceiling systems. New floor boxes and floor chases were installed to some areas with all services running outside of the tenancy installed in steel conduit. Particular attention was given to co-ordination with joinery, workstation items and Security requirements.
The existing basic troffer lighting system was supplemented with new down lights, strip lights and pendants. The existing Dynalite lighting control system was modified and expanded to control the new additional lighting zones and fittings. The lighting control system consists of touch screens, switches, and multifunction sensors. The existing troffers and loom system was modified/re-located to suite the new layout with extra sensors installed to control the new layout
The Emergency lighting system was modified / increased to suite the new layout. The base building system is a monitored system and this was updated to accommodate the revised Layout.
The communications system was all new works. The system consists of a communications room on each floor housing the cabinets and UPS systems. Each floor is backed up by a UPS and is connected to the Generator backed section of the Tenant DB. A TE-Connectivity cat6a structured cabling system was installed throughout the site. The tie cables from the GF to L2 consist of fibre and copper installed in steel conduit through all common areas.
The scope of works includes the supply of all labour, suitable materials, plant and equipment to complete the full Electrical Services package in accordance with the reference documents and includes, but is not limited to, the following:
Modification to the Base Building Tenant DB`s
Sub mains
Distribution boards
Internal lighting and associated sub circuiting
Internal lighting controls
Emergency and exit lighting
Power outlets
Floor Boxes
Telecommunications Equipment and cabling.
Cat6a Structured cabling system
UPS rack mount and free standing systems inc bypass switch. (Units supplied by NDIA)
The works involved the two level fitout of the North Sydney site to consolidate the North Ryde staff over two floors. There was a half floor adjustment/fitout of the North Ryde site as well. The North Sydney works consisted of a modification to an existing fitout to suit the new requirements. Some of the existing offices were left as was and the balance were modified for the clients requiements. The existing troffer lighting remained with new feature lighting installed throughout. The power services were modified to suit the new layout and with no recessed floor boxes allowed we installed under carpet floor trunking with pedestrian ramps. These were limline and carpeted over to blend in and provided power, data and AV service cables access from the wall outlets to the centre tables.
The data system was a patch by exception system and the existing system was to be reused as far as practical. All the existing data needed to be tested for compliance and identified before we undertook and relocations. The existing workstations were re-configured to a new layout which saw every workstation power supply and data cable removed, relocated, re-terminated and tested across the two floors. Carefull management of this saw only an extra 10 data cables installed to me the new layout.
The main works (stage 1) were completed in 10 weeks with stage 2 (Kitchen) and stage 3 (interconnecting stairs) completed across a further 3 months. The project ran smoothly with a good site team from Kerfoot and FDC and completed all stages on time. The client Goodman Fielder was more than happy with our works and we have kept them as a client and now have a service relationship with them. This was a successful project for Kerfoot.
Have you ever wondered “how does an RCD work?” This week at Kerfoot, we’re explaining all things RCD. Also known as residual current devices, your safety switch is there to keep you safe. It is important to know how this life-saving device works in order to ensure your home or business is as safe as possible.
How does safety switch work?
The switch works by continuously monitoring the electrical current in:
An entire building
An individual circuit
A piece of equipment
When a fault is detected, the RCD cuts off the power. Your system may be tripped by a short circuit, a circuit overload, or a ground fault.
When electricity moves through wiring, it travels through active wiring (for sending electricity) and neutral wiring (for returning electricity). When the flow between each type of wiring is equal, the residual current device will allow the electricity to function as normal. When an imbalance is detected, the safety switch will stop the flow of electricity.
Why does the RCD trip?
How does an RCD work when an electrical fault is detected? Put simply, it switches off the power. This can happen for a variety of reasons; however, the most common causes include short circuits, overloaded circuits, and ground faults.
Short Circuits
When electrical current travels outside of its intended route, it can miss its destination and continue to travel around a circuit. If the energy doesn’t reach the destination, the voltage is not reduced and the wires overheat as the current continues to move. RCD tripping will occur when a short circuit is identified.
Circuit Overload
Overloads happen when electrical circuits are overwhelmed. This can happen if you plug too many appliances into one power point/adaptor or if appliance voltages and power board capacities have been mismatched. Check the current recommendations of the side of your power distribution equipment as well as the voltage of your appliances/equipment.
Ground Fault
How does an RCD work when a ground fault is detected? A ground fault occurs when electricity travels outside of its intended route and enters the ground through a conductive surface. This can happen when a person makes contact with live electrical wiring. When a ground fault happens, the RCD detects the change in the return circuit and switches off the power.
Let’s Get Technical
How does an RCD work exactly?
We’ve given you a simplified version of how a fixed or portable RCD will work when a fault is detected. Check out this video for an in-depth look at the different parts and electrical mechanisms that go into a functional RCD.
If your RCD keeps tripping, it’s usually a symptom of a larger problem. Your equipment might be damaged or faulty, or there might be old wiring in your building. If these causes have been eliminated, there is a chance that your residual current device is faulty.
At Kerfoot, we offer RCD inspection, installation, and replacement services to businesses across Sydney. It is essential to ensure your building, staff, and guests are protected from electrical shock and electrocution. If you suspect that your device may be faulty, ask us to visit your property ASAP. Electrical safety is of utmost importance to our team.
If you do need a replacement, we can supply and install an industry-grade safety switch for your property. We offer a range of statutory testing services, so be sure to check out our website and let us know if you have any questions.
