I am running electrical on my patio. Got to about where going to put box for smoker and calling it quits for the day. Wasted 2 hours trying to put a GFCI outlet in 1 gong weatherproof box. Just not enough room and ended up using the 2 gong had for the other box. Running everything else off that GFCI. Now have to get another 2 gong and they not cheap, $30 with cover. Need to know length of cord for the 590?
