A generator is only useful if it is connected to your building safely. The most important part is the changeover: a switch that connects either the mains or the generator to your circuits, never both at once. Without it, generator power can flow back onto the supply lines and put anyone working on them at risk.
We install changeover switches, plan which circuits the generator will supply, run the cables, and make sure the generator is earthed. We also look at the size of the generator against the loads you want to run, so it is not overloaded as soon as heavy appliances start.
The setup is tested by running the changeover and checking that the chosen circuits work.
Problems we solve
- A generator plugged in with no proper changeover
- Power that can flow back onto the mains
- A generator that overloads or stalls under load
- No clear separation of which circuits it supplies
- Generator with no earthing
- Messy cables running through doors and windows
Our process
- 1
Plan the loads
We decide which circuits the generator will supply and total the load.
- 2
Fit the changeover
A changeover switch is installed so the mains and generator can never be connected together.
- 3
Cable and earth
Cables are run safely and the generator is properly earthed.
- 4
Test
We switch over and check that the chosen circuits run.
Benefits
- Generator power that cannot feed back onto the mains
- Only chosen circuits supplied, so the generator is not overloaded
- Safe, tidy cabling
- A tested changeover
