Cable routing - conduit fittings?

190 views, no suggestions. Surely more difficult question then "where to get 50ft ext3ension cord" :)

Will this conduit body work for routing cables in conduit through 3/4" floor? And if so, how to connect flexible conduit like grey Liquidtight or blue corrugated conduit to these openings?

I would get a roll of Liquid Tight flexible conduit and use that for everything. It's easy to work with and will give plenty of protection for the wires. I believe if you use a pull elbow like you linked to, you can insert the Liquid Tight conduit into the fitting and glue it with PVC cement just like you would with rigid Sch 80 conduit. Get rid of that blue fitting and use another like you have on the bottom of the box in the picture. For one #6 1/2" conduit should be OK, for 2 I would use 3/4". If you have the controller surface mounted, I would run the conduit right up to the controller, not just stop it at the floor....may as well protect the wires for the full run. I think 3/4" conduit needs a 1" hole IIRC....is this the info you were looking for?

Lciuidtite and EXN have their own ---Box Entry Connectors. As you surmise, Licuidtite is over the top for protection and any other plastic conduit will do as well for your application. If you don't want the installation to be staring back at you in the future, get the proprietary connectors for the type of material you use.
FWIW, my tail light and brake wires are led through EXN and I haven't noticed any wear or penetrations. I haven't driven in out too far in the bush, though.

No problem attaching Liquidtight to the box, they have proprietary connectors.

The problem I've been trying to solve, was to have a conduit AND a strain relief fitting on the box at the same time. Still don't know how, - other than leaving conduit loose at the box entry.

Grey fitting at the bottom is a cable grip - strain relief, not a conduit fitting. Would like to keep this grip, but don't know how to connect any conduit to it.

Westend, what is EXN?

And, conduit to controller would NOT go through the "floor". It's cables to Pos loads and cable to frame that go out through the trailer storage floor - probably through $2 electrical box on the floor.

Cables from breakers box to controller go up through the storage ceiling up into the bedroom. Storage ceiling is the bedroom night-table, see photo below. Bundle of wires at controller bottom are the wires coming from breakers in storage space below through the hole in night-table (aka storage ceiling in the earlier photos). Wires hanging from above are from solar panel. After the photo was made, I've opened 1" knock-out at the controller bottom, and clipped solar wire to the cab bottom above.

It's bad enough having the controller brick on bedroom wall, and I'm trying to avoid having any conduit there. Will try Wiremold duct in bedroom, though it's still ugly. Ideally, controller belongs in the storage next to breakers box, but it's too tight unless I evict the batteries from storage space to the outside OEM perch. Maybe I will.

Why do you want a strain relief for wires that are being run in conduit? What will be applying strain to said wires that needs relieving? :h

As you surmise, it's not really possible to put two different sorts of fittings in the same knockout at the same time...blasted laws of physics and things like that.

I thought that strain relief would protect wires from pulling out of the box - if the box falls down to the floor due to earthquake, flood, end of the world etc. OTH, conduit protects wires from damage while they are still attached to the box, but won't protect them from pulling out if the box drops down. I probably think too much :). Mexican air affected the brain.

Over the top for sure. If any of those things happen who cares if the box falls???

I ran the wires in cabinets, walls, etc so that they are not visible and all wires use split loom and some plastic clamps. SHOULD the 3 screws holding the box or the controller fail the wires will support the equipment. But I'd be wide awake during the earthquake with flashlight and absolutely the first thing I would check would be the box and controller. :S

I agree that you are over thinking this, and I also like Liquidtight. A couple of large zip ties (cable ties) will keep the wires from falling into the conduit if the box somehow falls, which is really unlikely.

Looking at your pictures, it doesn't look like it would be too hard to route the wires through the wall, instead of hanging where they are, then you could still use the strain reliefs. Maybe that would allow you to move the box out of the bedroom too.

If the box drops the conduit should hold the box and prevent damage to the wire.
Focus on the box attachment over the strain relief.

How are you fastening the box that it should be worrisome?
You could through-bolt the box onto a plywood backing board and glue/screw the box and board to the trailer framing and inner skin.

Sorry about the EXN, was having a brain fart, should have typed ENT.
