What kind of electrical wire does the hot tub use a three or four wire system. Im looking at instalation features right now it would be nice to have an owners manual to look at before a purchase. Thanks

All 220 volt hot tubs are 4 wire (2 hot, a ground and a neutral). In this case it will be a 50 amp line. The only other wire you would consider for the TV hot tub is if you wanted to bring a cable line, or satellite line to the TV itself. The TV has a standard male end coax cable fitting on the back.
