FAQ

What generator works with DTE’s meter plug?

One with a 30-amp (L14-30) or 50-amp (14-50) 4-prong outlet and no full-GFCI panel, sized up to 7,200 W (30-amp device) or 9,600 W (40-amp device), per DTE.

Can an inverter generator work with DTE’s meter plug?

Yes, if it has a 120/240 V L14-30 or 14-50 outlet and no full-GFCI panel. The Champion 201176 has both outlets.

Does DTE include the cord?

Yes. DTE lists a free 20-foot cord: L14-30 for the 30-amp device, 14-50 for the 40-amp device.

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. Use the meter hookup, an inlet or a transfer switch.
