If you have a generator, you must have a proper changeover switch — back-feeding the grid is dangerous to municipal workers and illegal. We install manual and automatic transfer switches sized to your generator.
What we do
Sizing the changeover for generator output, install at DB, test under load, certify.
Manual vs automatic changeover
Both connect a generator safely; one is hands-off.
| Type | How it works | Best for |
|---|---|---|
| Manual changeover | You flip it when power drops | Most homes, lower cost |
| Automatic transfer (ATS) | Detects outage, switches itself | Unattended / essential supply |
