In most outages a facility only needs a short list of things to stay on: controls that would lose their place, refrigeration or process heat, emergency lighting, security and network equipment. Backup power means working out that list and giving those loads a second source.
That second source can be a standby generator, a battery backup that carries equipment through short dips and the seconds before a generator starts, or both. The wiring is a big part of the job. Critical circuits usually get moved to their own panel so the backup source carries only what it should.
How it works
We go through your equipment with you and talk about what happens to each process if it loses power suddenly. You decide what has to stay on. We check those loads and lay out the options in a written estimate.
The work usually includes a critical-load panel, transfer switches and the wiring between them, plus circuits for battery backup units where you need them. Changes are scheduled with you so they don’t interrupt production, and we test the transfer before calling the job done.
