Generator transfer switch — manual or automatic, sized to the circuits you name
A generator transfer switch in Sacramento is the equipment that chooses the source. Manual for a portable generator; automatic when a standby unit should start itself. The circuits you want backed up, the service rating, and the generator size all have to match.
Manual, for a portable generator
You stand at the switch. A portable generator still needs an inlet. The circuits you name are what stay on.
Automatic, for a standby unit
The unit starts and the switch transfers without you at the panel. The service and the generator have to be sized together.
The circuits you actually name
Most jobs do not back up the whole house. The list is the design.
Generator transfer switch: the circuits, the service, and the generator have to match
A generator transfer switch is sized to the circuits you name, the service rating, and the generator you actually have — or will have. Manual or automatic follows the generator type, not a preference on the wall plate.
-
The list is the design
Which circuits stay on decides the switch. A whole-house backup is only if the generator and the service can carry that.
-
Portable still needs an inlet
The switch does not replace the inlet. A standby unit has its own connection.
-
What moves the cost
How many circuits, manual vs automatic, and whether the panel can take the equipment. A generator transfer switch in Sacramento is permitted when the circuit work is new.
When a transfer switch isn’t the right job
Choosing the source for the circuits you name is this job. A listed slide on this panel, or a battery path, are not.
A listed interlock on this panel is enough
That is generator interlock.
A battery is planned and the house is not ready
That is battery-ready electrical. The family overview is backup power.
Transfer switch questions
Is an interlock cheaper and just as good?
It is a different job. A listed interlock is generator interlock — mechanical, portable, whole-panel through the main. This job is a transfer switch for the circuits you name, manual or automatic.
Do I need an inlet as well?
For a portable generator, yes — generator inlet. A standby unit has its own connection.
Can it back up the whole house?
Only if the generator and the service can carry that. Most jobs name the circuits that matter. That list is the backup power starting point.
Manual or automatic?
Manual if you will start a portable generator. Automatic if a standby unit should start itself. The generator you actually have, or will have, decides.
Do you have to turn off your main breaker when using a generator transfer switch?
A transfer switch isolates the house from the utility before the generator starts. Follow the switch sequence we label on the enclosure.
