Default Finding buried spices and wires outside a JB

Recently I have been getting into inspecting and assessing mobile homes and other residences. Inspect, correct any deficiencies.

Recently an inspection moved into a full reno and when we started to take down walls I found a number of splices and wire ends just wrapped in tape just hanging out in the walls and ceiling without even a junction box.

During the inspection I had found a number of things that needed to be fixed but these few things had eluded me.

This worries me. I want to catch these things. And I am hoping that some of you may have some suggestions on methods or tools that would assist in finding things that are buried.

I have been considering an infrared camera, but I am worried that any extra heat generated by a buried splice wouldn't be enough to show through the wall.


Thanks

You can try your luck with a thermal camera. Not sure how well that would read through paneling. Being as you don't have xray vision you really can't be held accountable for things buried if there is no reason to suspect them (ie a circuit down). A tick tracer may help you find dead ended wires but that is about all the capability it would give you.

No-one is going to pay you to catch such splices.

There are a number of gadgets that are in wide spread use within the manufactured home industry that would not meet the NEC.

Such boxless splices are here to stay.

BTW, some flying splices date back eighty-years -- and are still conduction strong.

&&&

Stick built homes are designed to be modified an repaired after 'the build.'

RVs are designed to be discarded after eight-years -- pretty much. Yes, you can't even find critical new parts any more.

Manufactured homes are only one-step above RVs.

Move out of that niche as fast as your feet will allow.

Buried spices... I thought this thread was going to be about some "oregano" you found in a wall.

In all seriousness though, unless it's a buried splice that's failing so badly it's about to catch fire, there's little chance a thermal imager will be able to pick it up through drywall. A dead ended wire will have no thermal signature at all because there is no current flowing. There's really no good way to find these things unless they fail or you start ripping open walls.

I agree with your point. Not too much better than an RV. But it is a revenue stream that is actually fairly lucrative. Lots of labour. And in my area, Mobiles are required by law to be inspected before they can transfer ownership. Someone has to do it

Trailer parks, most often the final destinations for prom queens and tornadoes.

You might be able to find these things with a TDR, but it would be an awful lot of work and you'd wind up ripping open walls to discover you had a false positive.

Hardly worth the effort in an older trailer with the wall finishes they have, not like standard sheetrock and paint most often.

The bill could easily be where they'd rather the place had burned down.

Took the words out of my mouth, I have a TDR, but I can't see a guy using it to test every piece of wire in a mobile home. It's just not cost effective or practical.

There aren't a lot of partition walls in a trailer. Most of your walls and all of your ceilings are insulated. I don't know of anything that would work except a tear down.

Your contract might stipulate that you can't fix what you can't see.

We are not responsible for any existing defect in the wiring of the structure , and as such any repairs or remedy to same will be at extra cost above the price of this contract.

How are tornadoes and divorces alike in the south?


























Either way someone is losing a mobile home!
