Electrical Wiring

Adding AC (Mini-Split) to Current Configuration 2 forced Air Units

10 years ago

last modified: 10 years ago

I am adding a Mini-Split AC to my house.

Ductless High Wall Mounted Split Air Conditioning and Heating System. Variable Speed DC Inverter Operation Mode: Cooling and Heating. Capacity: 9,000 BTU/Hr. (3/4 Ton) Efficiency Rating: 23.5 S.E.E.R. Electrical Specification: 208-230 VAC, 1 Phase, 60 Hertz.

Current Configuration:

I have two AC dedicated circuits to two units.

Main Panel shows

1st two pole breaker as (2 30 amp)

2nd two pole breaker as (2 50 amp)

Both have a distinct ac disconnect box at the condenser.

Question: can either of these lines be used to supply power for the additional Mini-Split or will I need a dedicated line.

Reason for asking is the location of additional mini-split will adjacent to the two units and will be fairly far from the main circuit box for the whole house.

This unit is likely to require 15A @ 240 itself. You will need to run a dedicated circuit.
