Electrical – home not getting 220v

electricalelectrical-panel

The power company turned off power due to late payment.

The power is now on. Lights, tv, etc work.

What's not working is the water pump, dryer, ac/heater.

Called the power company and their side is good.

So here is what I have done so far:

  • Checked the inside house breakers, none tripped or bad.
  • Went outside of house to breakers for ac/heater and ones for water pump. None are tripped or bad.

That leaves the 100amp box/breaker just after the meter box. I have 110v and 99v coming from each leg thru the 100a breaker, checked between legs for amps and i get 20a+-. I should be getting 220-240a, right? So maybe the 100a breaker has a bad leg?

Next I checked the 100a breaker where the meter box wires screw into the 100a breaker. Now here is where I'm a little confused. I checked for the volts from meter wires and the ground wire from meterbox. One leg is 120v(good), the other leg reads 0v(no power?). The eletric company says all is fine on their side. Am I testing wrong?

You are mixing amps (a) and volts (v) in your description so I can't tell what you have measured from that. I seriously doubt you are measuring amps, so assuming you are measuring volts, having a 20V difference between the two legs indicates a serious problem with something; either your skill-set or the equipment. I agree that you should exercise the main breaker a couple of times; a bug may have crawled into it while it was off, and now its squished carcass is causing a resistance. After that, it's time to call an electrician.
