Manufactured Home Service Entrance

[Seven-Delta-FortyOne]

Looking at 550.10(I)2 2020 NEC/2022 California Electrical Code

Technically this would be a feeder, as the meter is on a pole a few hundred feet away with a disconnect.

Job I’m looking at is a home standby generator install. Here is a pic of how the feeder comes into the home underneath. Is that gap standard practice?



Behind the I beam, not visible in the pic, is a 2” pvc conduit down through the floor. 550.10 states there must be provision for attaching a junction box, but doesn’t say a box is required. Is this standard connection details for a manufactured home?

I need to intercept the feeder and reroute to the ATS, and I’m looking for the best spot, and also trying to find out if that will get called on inspection.

Here is a farther out pic for context.

I wouldn’t want that under my house wether it was allowed or not.

Definitely not Code compliant.
All the MH I've seen have factory conduit stubbed into the crawl space,
Normally it is a complete run of conduit to the source without any j box but there would be noting wrong with adding a properly sized and supported pull box.

Not Compliant whatsoever, but hey, makes your job easier tapping into that now so it worked out

 

[Seven-Delta-FortyOne]

Well, I won’t add to an already faulty condition. I’d rather fix it while I’m there. I add it to the bid, and they can take it or leave it.

When I saw that I figured it had to be wrong, but as I don’t work with manufactured homes, I don’t know if I was just ignorant.

Unfortunately there is nothing to attach a j box to, so I’ll have to get creative.

Oh, and that tap. It goes into about 200 ft of metal flex, snaked across the yard to another manufactured home on the lot. Still under construction. And the main home was put in a few years ago, by a reputable Mfr home company. Not sure what went wrong with the electrical.

 

[AC\DC]

Can’t you cut all that and install a jbox right there

 

[Ken_S]

I know in NJ HUD would have had all inspection responsibilities for the initial installation

Is it a Manufactured Home or a Mobile Home? There's definitely a difference in how they are regulated.

You going to fix that foundation to while you're at it?

 

[AC\DC]

As far as the junction box required and the 20 years, I’ve been doing it in Oregon. They’ve never once made us put a junction box. Straight pipe or an LB if the setter sucks at putting those mobile homes in.

It a manufactured home, it was built by the big local company that does them.

And yeah, those stacks of CMUs. I was a little surprised when I poked my head under there. They have a decent reputation, as far as I know. But…….

No one but a Select Few go under there, so yeah, the reputation is good

That’s what I’ll end up doing. I think I can attach it to a small spot that has plywood. The rest is insulation. It’s still gonna be a pain in the face to route that 3” up into it.

I expected it just to be piped the whole way. Then I saw that air gap and thought maybe it’s a manufactured home code? Earthquake joint? Maybe a plumber installed it and thought it needed an air gap?

Although done wrong, they did you a favor by leaving it so you could put a tap & pull box in!

The small wire looks like submersible pump wire, they probably tapped it there for the well pump. Here, they are bad to put #10 cu under the same lug as the AL mobile home feed. Looks like only three conductors too, which means no ground, unless they jumpered the neutral bar to the ground bar. Unfortunately very common with mobile homes.

 

[augie47]

to me this would be one of the jobs where "I appreciate the opportunity but my schedule won't allow me to take on the job"

With a permanent metal structural frame it would be a mobile home, the manufactured or modular home would typically have the streel transport frame removed and may or may not have steel I-beam support added for long open span.

 

[Electromatic]

Could you use some beam clamps and strut if necessary to mount a box to the beam?

 

[Seven-Delta-FortyOne]

I could find a place. But I’ll need 2 boxes, as there isn’t enough conductor length to go into the box and splice. And trying to work with that 3” won’t be easy as there isn’t a ton of space.

I think I’ll tell the customer that the only way I’ll do it is to put the genny and ATS out by the meter, and have the gas company set a new tank. I don’t want to even mess with that fiasco under there.
