Common questions
Answers about
mini-split wiring.

The breaker and conductor selection must follow the exact equipment nameplate and manufacturer instructions; it cannot be determined by tonnage alone.

This page covers electrical power and connections. Any HVAC equipment or refrigerant-line scope should be confirmed separately.
