Nearly all 120 receptacles that I check register 113-118 with an ampmeter.

I inspected a house last year, built in 2004, and the buyer didn't occupy for six months, then let her daughter move in.
Her daughter called me to complain about the electrical receptacles (blown tv, stereo, and computer). She just bought her third clothes dryer in six months. The appliance store said "this is the last one we will replace".
She called the electrical provider and the city inspector. They told her the ground wire is too small.??

I checked the inspection report, all in good order: 225 amp. service, #4 ground wire attached to the ground rod...

I went to the house checked the panel and ground wire/rod.

I then checked the breakers with an ampmeter.
120 amp read 140 amps
240 amp read 280 amps.
I checked the receptacles 140 amp reading. Dryer receptacle 280 amps.
I turned the oven on: Instant HOT!
I turned the cook top on: INSTANT VERY HOT!!!!

My conclusion was that the electrical transformer is not regulated and is overpowering the electrical to the house.
