Customer Question

I have 220 coming into my panel but when I put the main breaker on, I end up only having 110 working in the house. I tested the voltage coming into the main breaker and it is good. (220). But as I said when I put the breaker to the on position, I end up only getting 110. I even tested the bus connectors on the panel and they are showing only 110.
JA: I'll do all I can to help. How long have you been dealing with this?
Customer: FYI. I replaced the Main Breaker (100amp) and it did not solve the issue.
JA: Do you plan on doing the work yourself?
Customer: yes.
JA: Anything else we should know to help you best?

Test the panel as follows and let me know the readings.

  1. Test hot to hot on the incoming wire connections.
  2. Test each hot to the neutral bar.
  3. Turn off all branch circuit breakers and test on the buss, hot to hot
  4. Test hot to neutral from the buss.

before i do this is there anything you can tell me now that I should look for when I go out to the site? I may not get there until tomorrow. Strange how when the main breaker is off it reads 208volts coming in. But as soon as I flip it on, I have only 110.

You need to test step by step following instructions and give me the readings.
