I have a 4 rooms (living room, bedroom, kitchen and bathroom) in a apartment complex, 2nd floor. My living room is about 23'x13', bedroom is about 15'x11'. The ceiling height is about 7.6'. The 30A main fuse directly under the meter. There are two other 20A circuit braker fuses in the apartment. Currently I have 2 x 5000 btu window unit AC running 24x7 and my living room temperature is about 82° while the outside temperature is about 92°. My plasma TV consumes about 500W, microwave 1.15kW. With both AC, PC, TV, fridge and lights (all lights 11x23w or partial 5x23w CFL) on, I am able to use the microwave for a short period of time (minute or 2) without blowing the main fuse off. I have intention to replace the 5000 btu in the living room with a 12,000 btu (~1500W) portable with casters type. Do you think the 30A fuse will be able to handle the load when the TV, bedroom AC, and lights (5x23w) are on?
Thanks in advance for your time and help.
