Frequently asked
Is $1,200 a fair price for manual generator transfer switch installation in Maryland?
Yes. $1,200 is right around what most homeowners in Maryland pay. Anything from $270 to $2,475 is inside the normal range for a licensed electrician; above $2,475 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Number of circuits the switch covers and whether a larger interlock or switch is needed. Distance between the panel and where the generator will sit. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $2,475, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
