Whose Wire? What Wire? Where The Hell Did I Die?

[Meathead]

Ok.

So after many design changes over the last 2 years, my generator will reside under the front of the bus and the AC panel will be in the rear. I’m going to use the old threaded rod method to mount an onan rv genset right behind the front bumper. (Rear engine bus[emoji54])

My system is 30 amps. I already have 3-6ga wires in a flexible metal sleeve.


I WAS thinking that waterproof is not a necessity. But I will need a junction box at the genset, and that will have to be waterproof?

So should I pull out the 6ga wires and slip them in a waterproof sleeve like at Home Depot?



Or use a 6/3 extension cord like this?



Thanks for the help. [emoji3522]

The game is.......
Put the pics where they’re supposed to go.

i am not an electrician by trade and some of the sparkys on here might disagree?
two options i see.
are the 6 guage wires of adequate length from point A to point B.?
what guage wire does your equipment connections require as max?
6 is a little thick for small equipment but if you can find the correct lug connectors and shink wrap it could be a good long term carrier.
if you want to cut it out and run new exposed then you need an SJ cord instead of the S O cord listed the sj is listed for outside.
i only say this because you didnt say wher the wire is running as far as inside or out but i doubt a 6 guage wire was running inside.
this is just a bump for your thread.
i know what i would do but there more experienced opinions on here.
and pictures of what are thinking and or wanting to do always help

I would put the bottom picture in the top picture. The heavier insulation and more flexible wire in the extension cord would last longer than regular wire. I would then run it through flexible conduit to protect it from abrasion. It might not hurt to check some wire sizing charts. 6 gauge seems like it is pretty heavy for that amperage. I think the 8 gauge would be more than sufficient and 10 may be ok.

Answer is D, None of the above. I’m assuming that you want to run along the undercarriage. Yes?

Your cord solution is not allowed per the NEC.

Liquid Tight is not allowed because it doesn’t protect from physical damage.

What I think is that schedule 80 PVC conduit is what you want. Use stranded THWN wire. The conduit must be designed to drain

[Meathead]

Thanks everyone. From the above comments it sounds like I need a 30amp shore power cord and protect it with pvc conduit.
Correct?

Yes, I’ll be running the wires under the chassis C channel with a detour where the leaf springs are attached. There is one guy on here that ran his AC wires in the exterior rub rail. I can’t do this bcuz I have an EDoor in my way.

Can I use what I have now and put it in conduit?

A better picture of what I have now.

I'd use what you have ... as-is.

Well done.

Don't forget to put an anti-short bushing on that conduit.

If you are going to run your conduit/ raceway under your chassis, you might want to consider using EMT. 3/4” will be fine. Try to stay away from 1/2” if you can. It will give you better protection than greenfield or liquid tite flex. Not to mention the cost of the fittings for the liquid tite. Me personally I hate greenfield. I’ve seen way to many times that stuff get kinked or pulled to tight and cut the wire. # 8 THHN/THWN is good for 45 amps (75 centigrade.) If you are setting up a 30 amp system, #10 THHN /THWN will do fine.

I have no idea what to do here, but thank you for the Peter Frampton reference. You don't hear much about him these days. Do You Feel Like I do will now be stuck in my head for the next two weeks.

EMT. I had to look it up. That looks great!

I apologize Meathead. I should have told you what it is. Takes just a little practice to get the bending down but you can do it. I haven’t looked, but I bet there are plenty of you tube videos on how to bend EMT. It’s also pretty reasonable. If you run it under your chassis, make sure you use watertight compression fittings. Keep your bends below 360 degrees between junction boxes and you can use a fish tape to push in the conduit and pull your wire. If you don’t have very many bends, sometimes you can just shove the wire in without a fish tape.
