Okay here we go. 70 amp service into a main panel near electric service meter. The 70 amp service feeds a 100 amp sub-panel in the home. That just happens to be FPE with Stablok breakers. Which i see alot in this section of town. Electrical contractor comes and tells client that 70 amp service is fine. Now there is a forced air gas furnace and gas water heater but a 70 amp service is under sized correct? Also how does this ground look in the pic i attached? Do u like the double tap?
