Several key things to understand about electrical issues for tanning salons. Others feel free to join in - I'm no electrician! And ALL of this comes with the disclaimer.... this is for GENERAL information only - for specifics, consult a licensed electrician!
1. PHASE
Salons can have 3 phase power or single phase.
Single phase is sometimes referred to as "2 pole" - three phase as "3 pole".
In a nutshell - single phase uses "2 hots" and 3 phase uses "3 hots".
The 3 phase allows the pull to be "distributed" across more "hot legs" - and so, ultimately means you use a smaller size breaker than you would for single phase.
For example - a tanning bed that required an 80A single phase breaker would usually only need a 50A breaker for 3 phase.
Within 3 phase - you can have "Wye" (Y) systems and Delta. Delta can have a "high leg" that carries 240 current. This can be an issue when hooking up beds with 110 components (timers, fan controls,..). Nothing that is a deal breaker - but you have to pay attention when hooking things up.
