We'll do a proper load calculation and give you a firm price to add it safely (and pull the permit).

This is a ballpark estimate based on simplified assumptions — not an official NEC load calculation. Your real numbers depend on your exact equipment and existing wiring. A licensed Three Rivers electrician will confirm with an on-site evaluation. Questions now? Call 651-418-1476.
