What the Automatic Changeover Panel (Mains / Generator) does
A complete automatic changeover panel combines everything needed to make a standby generator fully automatic: an AMF controller, interlocked switching, breakers for both supplies, surge protection and metering — built to your load.
For sites still switching over by hand, it removes the delay and the risk of human error during power cuts, and protects the generator from being back-fed by the mains.
Signs it needs replacing
- Manual changeover causing delays and errors.
- Old panel overheating, undersized or unsafe.
- New generator installation or load expansion.
Get the right part first time
Send us these on WhatsApp and our engineers will confirm the exact part before you pay:
- Total load (kVA or amps) and supply type.
- A photo of the generator nameplate (make, model, kVA, serial number).
- Photos of the existing main switchboard.
Fitting notes
Panels are built to the site's load, cable sizes and fault levels, then installed and commissioned with a real mains-failure test. We survey the site first so the panel fits both the load and the space.
Frequently asked questions
How is the panel sized?+
From a site survey of your load, incoming supply and generator rating.
Does it include surge protection?+
Yes — surge arrestors are included, along with metering and breakers for both supplies.
Can it be added to an existing generator?+
Yes. Most generators can be upgraded to automatic operation with a changeover panel and AMF controller.
