A circuit breaker is the primary safety switch in your home’s electrical panel that protects your Heat Pump System from overcurrent. You can find the required breaker size (MOP) for every unit in our Technical Data sheets. Using the correct breaker is vital for the safety of your home and the validity of your Warranty Policy. If the breaker trips frequently, it may be a sign of an electrical problem or an undersized circuit. We recommend that a licensed electrician handles all the high-voltage connections for your Ductless Mini Split. A dedicated circuit is always required for our Central Condensers. Proper electrical installation is the first step toward a safe and comfortable home. It ensures your unit has a steady and safe power supply.
