Generator & Transfer Switch Installation on Long Island
Long Island storm season means outages, and a generator is only safe when it's connected through a proper transfer switch. Berman Electric installs manual and automatic transfer switches, interlock kits, and generator inlets so backup power feeds your home safely — never back-feeding the utility line.

Safety & code
Safety and code considerations
- A proper transfer switch or interlock prevents deadly back-feed to utility lines
- Generators are never connected through a suicide cord or backfed breaker without an interlock
- Critical-load circuits sized so the generator isn't overloaded
- All work permitted and inspected for safe, legal backup power
FAQ
Questions Long Island customers ask.
Why can't I just plug my generator into an outlet?
Back-feeding a generator through a regular outlet can energize the utility lines and electrocute a lineman — and it's illegal. A transfer switch or interlock kit isolates your home safely. That's what we install.
Manual transfer switch or automatic?
A manual switch or interlock is the affordable choice for a portable generator. An automatic transfer switch pairs with a standby generator and starts backup power on its own. We help you pick based on your needs and budget.
Which circuits should I back up?
Most homeowners prioritize heat, refrigeration, the sump pump, the well, and key outlets. We build a critical-load list sized to your generator's capacity.
Do I need a permit for a transfer switch?
Yes. Transfer switch and generator wiring requires a town electrical permit and inspection, which we handle for you.
