warp, I've seen people use a 555 op amp to build 12v delay relays. Also, there are lots of on-delay relays for sale on like mouser, digikey, newark, etc. The trick is finding one that supports 120v/20A, or just building a multiple relay setup, one with a delay used to trigger the main relay that can handle the current.
