Re: surge protection

I've done this in an MCC with a spare bucket, by flush mounting the TVSS in the bucket door, wired to its disconnect. Its critical on the TVSS to have short lead length. Could you put the TVSS on the end/side of the MCC? If its small enough you cound mount on the door and backwire it.
