Hey electure - good link. I didnt know those existed.
Hmm, if Randy wasn't in CA I'd say it was probably made by the former owner of this house!
I should show you guys my 50a 250v power strip.... Its a beast!
A friend's father down in trailerville had a contraption like that for his holiday decorations, 50amp stove cord jammed into two screwed together 4sq boxes w/ 5-15s. He got rid of it after the meter reader came out, found the future fire and called for a disconnect. (This was before PECO got around to putting remote-read meters in that section.)
