Trouble-Shooting Call

Electrician Vancouver ~ I got a trouble-shooting call last week, from a regular customer. I was told that one bank of high bay lights was not working.

When I went to the site the next day, I went to the breaker panel first to test for power, and then to a couple of rows of switches. After removing the covers to get at the switches, this is what I found…

 

 

The switch was shot. After replacing the switch I tested for amount of current draw on the switch, and found it to be within the switch rating. It is a 120 – 277 volt, 20 amp switch. The amount of current being drawn was 13.5 amps.

I closed everything back up, and the lights are now working OK again. This took about an hour to find and fix the problem, along with going to pick up the part.
