250 kcmil SER Cable Clamp

[Bama_Electrical]

I am on a rough-in and the GC is requiring 250 kcmil SER cable. I can’t find any clamp connectors to fit that size cable. Standard 2” are too small. What do y’all use when bring you 250 into a panel?

FWIW, Arlington has a 2" connector rated for up to 2.04" diameter cable, as well as larger sizes up to 4":

Their regular connector style (849S) only goes up to 2" trade size, which is limited to 1.75" cable diameter. Southwire 250 kcmil is 1.84" or 1.85" (3 conductor or 4 conductor), so I see that it wouldn't fit the regular style.

I think the key is finding the ones designed for round cables. One of my supply houses has them but many others don't even seem to know they exist.

If you had to you could use a Arlington 8416, 2.5" trade size MC connector.
