Hello everyone,

I have an exterior 400A disconnect switch-NEMA 4X with 2-6" nipple at the bottom entry was used for cables portable generator cable entry. I need to run (2) 2"C to this disconnect and wondering what is the best way to modify the 2-6" nipple so I can install the 2-2"C. Any thoughts?

Thanks,
 
A flat piece of aluminum to cover the existing holes and knock out new holes in it.

Thanks for your reply. Is there any reducer fitting can be used such as 6" to 2" or even larger conduit than 2" which I might can use?

There may be a reducing bushing that large but I'm not aware of one.

I've never even heard of a 6" to 2" reducing washer either, but, that don't mean someone doesn't make one.

I'm thinking that 6" is just way bigger than any reducer you are going to find. I'd do as jap suggests or if you have some old enclosure just sitting around cut the bottom out and screw it over the holes and use those knockouts or punch new ones.

I would hate to see the price of a 6" X 2" reducing bushing, if the disco is NEMA 4X, is it stainless?
 
If it is stainless have someone familiar with stainless welding/fabrication experience modify it for you, probably won't cost much much different than purchasing stainless fittings for it, if they do work for sanitary food production and such it won't even look like anything was modified when they are done.

It's easy enough to make a pair by punching holes in two pieces of metal, and no hardware needed.

Use 7" or 8" squares, or two rectangles if the two existing knockouts are close enough to each other.

The outside doesn't have to be round, and the new holes don't have to be centered in the old holes.

I'd put the aluminum plate in before I'd do that.
