Why Is My Voltage Not Right After My Circuit Breaker Tripped Off?
How to Restore an Electric Circuit: Check the voltage of both legs of power to ground, or test receptacle outlets and devices in the home. If it is found that the voltage is still not correct you may need to call a qualified electrical contractor to make a few tests to identify the problem and make the necessary repairs.
Understanding Circuit Breakers and Home Electrical Circuits
[ad#block]Electrical Question: A circuit breaker tripped off and now any circuit I turn has low power.
- My electrical question is:
- I have a pole building that draws power from my home. I tripped a circuit breaker this morning and now any circuit I turn on drops power to around 70 to 40 volts and the opposite lug jumps to 180 volts to 200 volts.
- Could it be a bad main or the service lines from the house to the shed?
- I have checked all outlets and lights and nothing is burnt or wired wrong that I can tell.
- Every thing in the pole barn is in conduit and all was working just fine before the outside outlet shorted.
- The electrical is only 5 years old and I have a square D box in both the house and pole barn.
Additional Comments: Great information! I have wired several homes and out buildings over the years with no problems, but can still learn from this website!

Thanks for your electrical wiring question John.
