Wife was complaining that my UPS in the garage kept making a clunking sound and then the lights would flicker.
So I went down and watched, and sure enough the lights would flicker and the UPS would clunk. Looking over the voltages I would see a 20v drop and then it would come back. I happen to have a UPS on the 2nd leg of our box so I watched that one, and the voltage never shifted.
Turned off the breaker box, pulled the cover, pulled the breaker in question. boom, clearly it was a corroded contact causing higher resistance, and heat, and causing brownouts.
$8 later were back up and running, and I can sleep safer knowing at least THAT breaker is not going to start a fire.
If inserting a plug feels loose then just bend the contacts. No need to replace anything if looseness is the only problem.
umm… no. Because if its loose that means the internal springs have worn out and are not firmly holding the blades on the plug. You can try a different plug and see if its just as loose in the receptacle but if it is, then you need to replace! Now i will make exceptions for Christmas lights because the blades on those are so thin and weak they often require adjustment.
