And folks wondered why I used 10 gauge marine wire and Hubbell hospital green dot 20-amp receptacles in Quicksilver. I picked up half a pallet of brand new receptacles (black) at the Lockheed auctions for fifty cents a pound. For some reason the contacts, strips, wipers, and screws were nickel plated. Loved the Antelope Valley for 6-months worth of Thursday's auctions. A 300 lb spool of 8-gauge aviation cable cost me $150. I sold a quarter of it for $500 in a dozen or so sales to pilots and PMA mechanics.
When you go to Home Despot or Lowe's, choose nylon rather than plastic receptacles and plugs. Then you're assured of getting fire-engine resistant quality.
