A 25 amp circuit breaker is the correct size for a 24,000 BTU mini split. Using a 30-amp breaker is fine too.

What size breaker do I need for a mini split AC?

You need a minimum 25 amp breaker for mini split systems up to 24,000 BTU/2 tons. A 30 amp breaker is sufficient for 36,000 BTU/3 ton systems, and a 50 amp breaker meets requirements for larger units to 60,000 BTU/5 tons. All the details follow.

What size wire is needed for a mini split?

Can you plug mini split into outlet?

Smaller mini-splits (12,000 Btu or less) can be plugged into a standard 110 volt outlet, but larger units often require a 220 volt outlet. Depending on the size and number of mini-splits you plan to install, modifications to your existing electrical panel and outlets may be necessary.

How much power does a mini split use?

The average wattage of a mini-split is about 600 watts. The average household in the US pays about $0.13 per kWh. If you were to run your mini-split heating and cooling system 24 hours each day, you’d use about 432 kWh per month, totaling about $56 in electricity costs.

Where are GFCI breakers required 2020?

The NEC mandates GFCI protection in many areas of the home: bathrooms, garages, outdoor receptacles, crawl spaces, basements, kitchens and anything within six feet of a sink or water source. While that may seem like a lot, the entirety of a home is not covered.

Does HVAC need GFCI?

GFCI protection is required for each HVAC unit rated more than 50 amperes. GFCI protection is never required for an outlet supplying an HVAC unit.

Is there a difference between GFI and GFCI?

Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.

How many outlets can be on a 15 amp circuit?

8 outlets

Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.

Can you put 12-gauge wire on a 15 amp circuit?

Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.

How many outlets can you run off a 20 amp breaker?

The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.
