If you want all of the rigs in the same room , you probably need to contact your electrician/wireman.

Theoretically, any normal room should have 2 circuits, one for the airconditioning unit and the other one for your light fittings etc.

Now lets say you want to run 5 rigs. You woukd probably need in total 3 circuits in your room. 1 circuit can easily run 2 rigs.
