Generator Interlocks, 50A Inlet Boxes & Transfer Switches in Downriver, MI
When a storm knocks out power Downriver, backfeeding a home panel without a listed mechanical interlock or transfer switch is dangerous and illegal. TradeScope pre-scopes your main panel and exterior meter wall from a photo and matches you with ONE local shop whose Michigan electrical contractor license and insurance certificate we verify in writing. Free for homeowners, with no bulk lead-selling.
What we check from your photos
To confirm which listed OEM or UL-tested mechanical breaker interlock plate fits between your main breaker and top branch spaces.
So the electrician knows whether two adjacent spaces next to the main breaker need to be freed.
To plan the weatherproof 50A (SS2-50P) or 30A (L14-30P) power inlet box and check if an exterior main disconnect is present.
Why homeowners use TradeScope
You are not hiring us to do the electrical work. TradeScope is run by Scott Lynch, a Southgate resident and an electrical apprentice working full-time. You are using an apprentice's eye to pre-scope the job and a written verification standard (Michigan license number and Certificate of Insurance on file before a match) to connect with one independent licensed shop.
Frequently asked questions
What is the difference between a generator interlock kit and a manual transfer switch?
A listed mechanical interlock kit attaches to your main panel cover so the utility main breaker and generator backfeed breaker can never be turned on at the same time. That lets you power any circuit in your panel (within your generator's wattage) at a lower install cost than wiring a separate multi-circuit transfer switch.
Should I install a 30-amp or 50-amp generator inlet box?
Homeowners running 7,500W to 12,000W portable or tri-fuel generators typically choose a 50-amp NEMA SS2-50P inlet box on a 2-pole 50A breaker for full 120/240V capacity.
Do generator hookups require an electrical permit?
Yes, and every shop on our roster carries a verified Michigan electrical contractor license and Certificate of Insurance in writing and pulls municipal permits.
What does TradeScope cost?
Nothing for homeowners. Partner shops pay a 10% referral fee only on completed work ($0 upfront).
