here's the quick and best answer. Call an electrical contractor and tell 'em your opening a spa with (4) 1000 watt tanning booths, etc, etc. and see if you have enough capacity. If no, ask him or her what you need to do. We can't tell you anything from those fuzzy, dark photos of nothing, let alone know if it's 'connected' or not. So very, very sorry. Now I'm sad too.
