I have always wrapped our outlets with electrical tape.No,  it's in a plastic box.

I had one of those plastic bed liners and I thought no way I need to tie this stuff down.. well I had to cross Silverado trail which is a secondary road but 55 MPH and very busy.. so I gas it and promptly deposited the entire load in the middle of the road to skidding traffic from both sides  OUCH.. no one hit any and it all landed in a nice thump so nothing hurt.. reloaded it and then tied it down.. other wise I rarely if ever buy anything other than a few bedding plants for my gardners to plant..

They are $5 at Wal-Mart for the plastic ones.
