Power out in garage no GFCIs in garage, no apparent breaker trips

Hello everyone,

I couldn't figure this out so i figured I post here.

I did go through Troubleshooting a dead receptacle or light, Basic Terminology & Other info

Read more: Electrical - AC & DC - DoItYourself.com Community Forums

Background

Was operating a table saw + AC + shop vac + lights... Power goes out. I procede to check the circuit breaker boxes, No switches tripped but Idecide to flip them off and on anyway. Problem not solved. Went inside Located 3 GFCs 2 in the bath 1 in the kitchen. push Reset and test, made sure they were all working. Power is still out. Any suggestions on what to do next?

The house is in Sacramento CA and its 1905. I just moved in 1 month ago.

Do you mean you have more then one breaker box? If so does the garage have its own subpanel? Is the garage attached or detached? Do you have a multimeter, preferably analog? (A non contact tester won't work.)

The high startup draw of the saw may have caused a connection to fsil. Can you measure voltage from hot to ground and hot to neutral?

I not sure the terminology, but theres another breaker box that was added for a additional room. It looks likes its connected together.

The garage is detached and there are no obvious electrical wires going to the house, maybe its underground?

I do not have a multimeter, but would by one if it can help with this problem and if it helps with changing ungrounded outlets( project down the road).


I did test all the outlets with a nightlight and they are all out in the garage.

Another piece of info, I was running the saw fine for a few seconds then halfway through the cut the power cut.

A cheap ($8-$15) analog multimeter is useful for many things. Don't get a digital though they can be problematic for AC use. You need to open all the garage receptacles and switches, check that all screws are tight, move any back stabs to the screws, and redo all the wire nut connections

It sounds like you have a main panel and a sub panel.
The sub will be fed from the main. The main can be identified by being where main lines come in from street.
Did you turn off and turn on every breaker?
If not, turn off every breaker at sub.
Turn off every breaker at main.
Then turn them all back on starting at main panel. Sometimes you can't tell by looking that a breaker has been tripped.
If you already did all this, then you will still get to the bottom of it here.

Glad you got it. Thanks for letting us know.

Terminology help: It is just "circuit breaker" not "circuit breaker switch".
