3D Electric offers Generator Transfer Switch Installation Ypsilanti, MI for houses in the city, Ypsilanti Township and Superior Township. The switch sits between your meter and your panel, and it lets the house run on DTE power or on the generator, one source at a time. Use this page on Generator Transfer Switch Installation Ypsilanti, MI to see which switch fits a historic district house, a township ranch or a Superior Township home on acreage.
Our family-owned shop is in Belleville, 10 to 12 miles east on I-94, and some Ypsilanti Township addresses carry the same 48111 ZIP code as our office. We are licensed and insured, and our crews have installed both 200 amp and 100 amp automatic transfer switches. If you still need the generator itself, start with standby generator installation in Ypsilanti. For our electrical work and other local pages, see 3D Electric in Ypsilanti.
Lectro's tip
Before storm season, write down the five things you can't go without, like the sump pump, furnace and fridge, and tape the list inside the panel door.
What the September 2026 storm showed Ypsilanti
On September 3, 2026, a severe storm and tornado warning left about 7,486 customers dark in ZIP 48198 and another 2,876 in 48197. Poles and lines came down on Cross Street, Maple Street, North Adams and Emmet. DTE says outage time in Ypsilanti fell 54 percent last year and plans more than 100 miles of tree trimming. That helps, but old trees near the Huron River still drop limbs on wire.
One source at a time
A transfer switch disconnects the house from the utility before it connects the generator. That matters while crews rebuild a street like Emmet. A generator tied into a panel with no switch can push power back through the meter and onto a line the crew thinks is dead. That is called backfeeding. It can kill a line worker, and it is illegal.
Cords versus a switch
Heavy cords run from a portable generator straight to a fridge or a space heater need no switch. A cord plugged into a dryer outlet or a wall plug is a different thing. It backfeeds the panel, and it can start a fire. If you want generator power in your house wiring, you need a switch or a listed interlock.
Historic district houses: the panel comes first
The Ypsilanti Historic District, which takes in Depot Town, is the second-largest contiguous historic district in Michigan.
What we often find in older Ypsilanti houses
A fuse box, or a breaker panel whose maker no longer sells parts.
A 60 amp or 100 amp service feeding a house that now has central air.
A full panel with no open slot for the generator breaker.
A transfer switch can't fix a tired panel. If the panel needs replacing, we plan both jobs for the same shutdown, so the power goes off once. Our electrical panel upgrades for Ypsilanti houses page covers that work. If the switch or conduit will show on the front of a historic house, ask the City of Ypsilanti whether exterior changes need a review.
Township ranches and Superior Township acreage
Ypsilanti Township has about 24,485 housing units, and many of its houses already have a 200 amp service. For whole-home backup there, the usual pick is a service-entrance rated automatic switch. It mounts between the meter and the main panel, has its own main breaker and moves the whole service at once.
Load management for central air
Load management modules pause the air conditioner, an electric dryer or an EV charger when the generator is close to full output.
Space and distance in Superior Township
Superior Township is far less crowded, with about 421 people per square mile around Dixboro and Frains Lake. If your home runs a well pump, that pump needs 240 volts, so the switch and generator must feed both sides of the panel. On a big lot the generator pad may sit well away from the meter, and a longer run adds wire and trench to the job.
Picking a switch for the generator you have
Here is where Ypsilanti homes usually land:
Your setup | Switch we usually fit |
|---|---|
Standby generator, whole house | 200 amp service-entrance automatic switch with load management |
Standby generator, essentials only | Smaller automatic switch feeding a subpanel of chosen circuits |
Portable with a 240 volt outlet | Manual switch or panel interlock with an outdoor inlet |
Portable with only 120 volt outlets | No panel connection; heavy cords to single appliances |
Each generator brand uses its own control wiring between the switch and the unit. We install Generac, Honeywell and Kohler home standby generators and wire the matching switch. See Generac home standby installation in Ypsilanti for that pairing. If a portable is all you need, our interlock kits for Ypsilanti portables are a simpler option than a separate switch.
Three permit offices around Ypsilanti
Transfer switch work needs an electrical permit and an inspection. Which office handles it depends on where the house sits, not on the city printed in your mailing address.
City of Ypsilanti: the Building Department uses its 2026 Trade Permit Application.
Charter Township of Ypsilanti: the township Building Department issues the permit and does rough and final electrical inspections.
Superior Township: the township has its own electrical permit application.
Confirm current requirements for your address with that office. Our Michigan generator permit guide lists what inspectors tend to check on a switch job.
Install day and what moves the price
Quote visit. We look at the meter, the panel and the wall where the switch will hang, then give you a written estimate.
Permit and shutdown plan. Some service-entrance jobs need DTE to disconnect and reconnect the service. You hear that plan ahead of time.
Mount, wire and inspect. We land the service conductors, run control wiring to the generator, and the inspector checks the work.
Live test. We cut utility power, watch the generator take the house, then restore DTE power and watch the switch hand it back.
Cost factors
Price depends on automatic or manual, the amp rating, any load modules, wire length and whether an older Ypsilanti panel needs work first. Quotes are free with no hidden charges, and financing is available. The home generator cost guide shows where the switch fits in the total, and our transfer switch installation overview explains the switch types in more depth.

Frequently Asked Questions
Not always. Many Ypsilanti mailing addresses are in Ypsilanti Township or Superior Township, and each runs its own building department. We check which office covers your property before filing, and you can confirm current requirements with that office.
Usually not on the fuse box itself. The switch needs a sound breaker panel behind it. We can replace the panel and add the switch in one shutdown, so the house only goes dark once.
A whole-home setup on a 100 amp service usually gets a 100 amp switch. If you plan a service upgrade soon, it can make sense to size the switch for the new service. We sort that out at the quote visit.
It can, if the generator and switch supply 240 volts and the generator has enough capacity for the pump to start. We add the pump to your load list when we size the system.
Yes. It is common to add a switch during a panel replacement. Pick the generator brand first if you can, because control wiring differs between brands.
Have it tested under load once a year during generator service. The weekly exercise run often leaves the house on DTE power, so a stuck switch can go unnoticed until an outage.
