Frequently Asked Questions about MRCOOL DIY 5th Gen Mini Split - 6-Zone 55,000 BTU Mini Split Condenser 230V with 18K + 6K + 6K + 6K + 6K + 6K Ceiling Cassette Air Handlers DIY5-6ZC-55HP-18K6K6K6K6K6K

Most Frequently Asked Questions

Yes, you need a dedicated breaker for a mini-split as required by electrical codes - mini-splits must have their own circuit and cannot share a breaker with other appliances due to their high electrical load and safety requirements
MRCOOL mini split breaker requirements vary by capacity: 9k BTU uses 15A, 12k BTU uses 20A, 18k BTU uses 25A, 24k BTU uses 30A, and 36k BTU uses 50A, but always verify your unit's specific MOP rating on the nameplate
MRCOOL 18,000 BTU units require a 25 amp breaker, 12 AWG copper wire, and 230V power supply, though you should always confirm the specific MCA and MOP ratings on your unit's nameplate

Other Questions

MRCOOL mini splits consume around 1,500-1,800 watts and draw 12-15 amps for an 18,000 BTU model, with usage varying based on unit size and SEER rating
MRCOOL DIY mini splits usually provide 12-20 years of service when properly maintained.
