Here's a twist on the usual story.
We had one circuit in the house that was sometimes used for an electric
iron. I had noticed that when the iron cycled on and off the lights in an
adjacent room would dim an brighten in time with the iron. This is a
manufactured home built by a supposedly reputable company in Plant City,
I had figured that this was caused by some cheesy back stabbed receptacles.
I planned to chase the problem down some day. Today, my hand got called.
With no particular load on the circuit it died.
I went through the usual. Checked the breakers etc. no problems there. Then
I noticed that two receptacles on the string were on but the rest were out.
So I started pulling receptacles out trying to find the loose back stabbed
unit. The first three were not at fault. Then I went to a fourth one which
was in the bedroom. This outlet had a plug strip in it that was lightly
loaded with a lamp, a clock and a cordless phone base. The breaker was back
on so I could see what was live and what wasn't.
When I went to pull the plug strip out, there was a nice blue flash and a
pop and just like magic all of the dead circuit came alive.
Aha, the culprit is found. Power down, remove the cover plate, pull the
receptacle. What a botched up job. The back stab wires were all nice and
snug. Of course one of the neutral wires had a little more that 1/2 inch of
copper showing, but that wasn't causing the problem.
There was one hot wire neatly hooked under a nice brass screw. It looked
good except that the screw missed being snugged down by about an eighth of
an inch. What a helluva good inspection that job got. But it lasted over six
years before it finally failed.
Any way, I ran up to good old HD and got a 10 pack of the better outlets.
When I get those all installed, I will get another bunch and keep myself
busy. And they won't be back stabbed.
Just thought you might be interested that it is not always the cheap outlet
with the chintzy back stab that gets you, but piss poor workmanship.
