Connect UF-B cable totransfer switch / Inlet box


Hello,

I need to run a UF-B 6AWG cable from Reliance Q506A transfer switch in the basement to the Inlet box outside. It is about 1 1/4 '' wide.
I cannot connect directly UF-B cable to the Transfer switch, since the wire is flat and is a large diameter than the opening for the fitting on the Transfer switch.

I probably need a junction box to transition UF-B to four single wires that I can connect to a Transfer switch and Inlet box. What are the models of the Junction boxes that accept flat UF cable. Will I need any extra fittings for the junction box? What type of fittings. I wont to run single wires in the conduit from Junction Box to the transfer switch / Inlet box.
In addition, since inlet box will be outside, 40+ feet from the place where it comes out from the basement, I will need a waterproof junction box. is it exist for the UF-B cable?
I do not have an Inlet box in my hands yet. Maybe there is a chance that I can connect UF-B cale directly to it somehow.

Related question I have. is the code allows to run UF-B cable along the outside house wall about 2 to 3 feet above the ground without the conduit?

Thank you,
Regards,
Vad

Why did you run UF, and secondly, just use a connector that will accept UF.

As far as I know you would need to run that wire in conduit above grade. Dont hold me to this but I have read that uf-b doesnt need to be ran in conduit as long as its buried 24" (might even be 18").

It doesn't need to be in conduit if run along a structure.

I already bought an UF-B. I do not have a choice here. I would appreciate if somebody could send a link to the junction box that would accept UF cable.
Since I see different opinions, where can I double check whether UF can be run along the structure? Is this a state / county specific? I also have a concern about strong sunlight that the last 5 ' of cable will be exposed to.

Thank you,
Vad

UF is sunlight resistant, read the jacket... and its in the NEC that it can be exposed. I still dont know why you want a jbox for the UF, just terminate it like any other cable.

You should have a knockout big enough to accept a clamp connector that your wire will fit through

A knockout in my transfer switch is 1'' round, My UF-B cable is flat and 1 1/4 inch wide.
Should I somehow widen the knockout hole? Can somebody send me a link to what type of fitting accept UF cable.

Thank you

You need to make a larger hole, to fit an appropriate cable clamp.
