DTE’s generator plug, in one picture
The short answer
DTE installs a device between your electric meter and the meter socket. Your portable generator plugs into it, and the house runs through your own breaker panel. DTE sells it as Surge Protection Plus, made with GenerLink. (DTE plan page)

Do you qualify?
Yes, if
- You’re a DTE residential customer in good standing
- Your service is 200 amps or less (look at the main breaker)
- Your generator has a 4-prong 30-amp (L14-30) or 50-amp (14-50) outlet
- Your generator does not have a full-GFCI panel
Look elsewhere if
- Your service is over 200 amps
- Your generator only has regular household outlets, or a full-GFCI panel
- You need more than 9,600 running watts
- Nobody is home to roll a generator out (a standby starts itself)

How to get one
- Check your main breaker. It should say 200 or less.
- Check your generator’s outlet. L14-30 or 14-50, and no full-GFCI panel. Shopping for one? See generators that fit.
- Call DTE’s Surge Protection line. (833) 452-0224.
- DTE installs it at the meter. No appointment or permit, usually under 30 minutes, with a brief power interruption. Coverage starts 15 days after install.
What else comes with it
Whole-home surge protection with warranty coverage up to $5,000 per event for appliances and $1,000 per event for electronics, and a free device replacement if a surge damages it. (DTE plan page)
Questions people ask

Is DTE’s generator plug a GenerLink?
DTE says it partnered with GenerLink on the Surge Protection Plus device.
Do I need an electrician or a permit?

Can I cancel DTE Surge Protection Plus?
Yes. DTE lists a $150 early termination fee if you cancel within 12 months of enrollment, plus a separate device removal fee.
Does my meter keep running while I’m on generator power?

Two rules that save lives
Never run a generator in a garage, porch or near a window. Keep it 20 feet out, exhaust away.
Never backfeed through a dryer outlet. A ‘double-male’ cord can electrocute a lineman down the street. Your plan uses only safe, legal ways to connect.
