Permits for backup power
Generators and batteries need a permit and inspection. Batteries add a utility interconnection application, approved at the utility's pace. We file it, line up gas work, and itemize the fees.

Backup power questions
Is plugging a generator into a wall outlet really dangerous?
Yes, and illegal. It can energize utility lines and hurt a lineworker. An inlet box and interlock is the safe way.
What size portable generator do I need?
5,000 to 7,500 watts covers essentials in most homes.
Do you charge for the quote?
No. An electrician looks at the job in person and quotes it, free.
