Hey folks.
I am trying to figure out a problem with the power supply in my shop.
We were working in the shop one evening when we had a power failure. I finally tracked it down to the main breaker for the shop which is a 200 amp which has never tripped since it was installed.
The maximum that we were drawing was 98 amps calculating lighting-1460 watts 12 amps, RPC- has its own 40 amp breaker, radial arm saw-10 amps, bandsaw-12 amps, air compressor-12 amps, water pump- 12 amps.
The day was rainy with some lightning and wind, though no lightning really close.
My question is if the power load was nearly half of the rating of the main breaker could a spike on the line cause the breaker to trip?
The 120 v loads are fairly well balanced and all wiring in the building is in emt. The building has its own service and is grounded properly.
Thanks in advance,
Brad
