  • Cord failed near end

    The cord stays paired to the surge suppressor so it's not like it gets plugged in and unplugged. Also been plugged in at the house for a couple of months.

    We did have a power outage the other day for under 5 minutes. Do not know if this was related.

    I noticed when running the jacks the other day the voltage dropped by a lot (down into the 11's). Thought nothing of it. Fast forward to this afternoon, I ran the slides out to check things and see what needed to be moved for the annual inspection trip so I can go get the registration. When running the slides all out at once (yes I do this from the manual panel on purpose) I checked the battery level on the panel and it was E. Looked up to notice the voltage gauges were all dark.

    Start checking, Main power breaker on, so go around to the house panel and its tripped (note I still have a 30A 2 pole breaker for the camper but this has never been an issue). I flip it back on and it holds. Back around to the camper and everything is on and normal. A while goes by and I go to check the battery charge gauge in the hold and note it's discharging. Back inside, the voltage gauges are dark again. back to the house panel and it's tripped.

    Flip house breaker on again, and she thought she heard it trip. So I walk back over to see, and it's still on, but as I walk away I hear it trip. So, I walk around to the camper with the intention of unplugging the cord from the wall to determine if it's camper or wiring related. As I walk up, I notice the rocks under the cord are black and then as I unplug the surge protector, I notice some scraps of string on the ground burnt. Originally they were in the rocks but I picked them up to see what they were and dropped them back on the driveway.

    I did not get a picture before I cut the insulation back, but this is what I found at the edge of the strain protector inside the cord.

    And After I stripped back the strain protector a bit:

    Looks like the insulation between the black hot and ground became compromised some how (strings were wet and main cord black insulation was cracked). We did have some freezing conditions over the past few weeks and some rain this week.

    The bright shiny green and other insulation colors are where I nicked them with the razor knife.

    MORAL: Check the cord ends. Don't know how it got damaged or how long it was off, but thankfully the breaker caught it. Surge protector pre cord showed no signs or indications of anything wrong with wiring. I don't even think a hard wired one would have caught it b/c it was a direct short vs broke wire. the wires you see are all still in tact with a few melted conductors.

    Joseph,

    Is this an homemade cord? The end looks like a bolt on aftermarket end and not the usual factory molded to the cord end.

        Joseph,

        Is there any strain relief when the cord is plugged in? I wonder about these cords beginning to fail internally or from insulation cracking to allow moisture in. I will be more diligent in routing my cord through the ladder to take some stress off.

          In addition to checking cord ends/connectors, coiling a cord affords the perfect opportunity to inspect for nicks, cuts and abrasions down its length.

            The first picture is after I put a generic 14-50P on to replace the moulded one. Note the third and fourth pics where you can see the moulded end.

            The strings were wet, how water would have gotten in is beyond me.

            The surge protector does the strain relief out of the house to where it lays on the ground.

            There was no evidence of nicks on the cord. There are the generic scratches in the outer layer but none deep enough to expose any of the internals. More like sandpaper ran down it's length when coiling it on the ground. The only signs of insulation failure were at the ends. I might be able to pull the outer shielding from the trash and get a pic as I did a long slice and then circumferential cut to get to the failure point.

              I wipe the cord down after each use and hope this may catch and issue. But until now its just been to wipe dirt off.

                  I have a southwire surge guard between the end that failed and the plug on the side of the house.
