Seeking Replacement Spring Clips for Bulldog Electric 400A Fused Disconnect

[brycenesbitt]

We're cleaning spiders out of an in-service fused shutoff made by Bulldog in Detroit, installed in the late 1950's.

The thing still has a paper label saying "oil every six months".
But more importantly it's got clips on each fuse lug, presumably to keep tension.

One of those clips is not in good condition, and crumbled immediately. Can anyone help suggest a part
number or source for replacement spring steel clips ?

However that's listed for 35-60 amps, and not listed for this panel. I work in jurisdictions that -- a lot of the time -- cares a lot more about a literally read of the sections of the NEC about listing requirements, compared to accomplishing the goal.

Any way to get an OEM replacement? I did check eBay but can't even find a used shutoff switch of the same era.

Give these guys a call, they might be able to supply you some used OEM ones. Or the gear that has them installed.

You might find a bus plug of the same vintage for some spring clips, they were the same on Bulldog bus way products then later ITE.

But judging on the amount of corrosion I see, you may need more than one. The spring steel clips don't survive well in atmospheres that are acidic or corrosive, just trying to wash them can at times make them break just putting mild acidic cleaner on them.

A buss #7 would be the listed size for a 400A.
