What Kind of Circuit Does a 115V Mini Split Need?

Use the requirements for the indoor and outdoor units you are pairing. The 115V label alone cannot tell you the breaker or fuse size, wire size, disconnect, connection method, or whether an existing circuit is suitable.

What do the circuit numbers mean?

The manual gives two important circuit numbers. Minimum Circuit Ampacity (MCA) is the minimum current the wiring must safely carry. Maximum Overcurrent Protection (MOP or MOCP) is the largest breaker or fuse the manufacturer allows. An electrician should use both numbers when planning the circuit.

Can you use a regular outlet or extension cord?

Do not assume so. The current DIY 5th Gen documents show field wiring at the indoor unit, while EasyPro and Select documentation use their own connection details. Follow the manual that matches your indoor and outdoor model numbers.

Who should make the final call?

A qualified electrician should check the equipment instructions, local requirements, wire path, disconnect, grounding, protection, and the rest of the power source.

Your next step: Open the product page and manual for the system before anyone plans or installs the circuit.
