I find when I use my 30 amp autoformer with my surge protector on a site with good voltage sometimes my surge protector will shut down because of over voltage.

Usually my voltage without autoformer will be 123 volts and with autoformer might be around 128 volts. These voltage readings are from the surge protector display.

Autoformer is closest to electrical stack and then surge protector and then trailer cord.

Anyone else have this problem
