    Hi Mike,
    Each AC Unit will require it’s own dedicated circuit to avoid tripping the circuit breaker of a shared circuit with other devices. Please consult the equipment specifications label on each AC unit or the installation manuals to identify the required circuit. The specifications will state the required amperage and voltage for each air conditioner which will be essential for installing the proper circuits. Once the required circuits have been installed the AC Units will not trip the circuit breakers.
    I hope this helps you,

    I have two 25k BTU Air Conditioners. Each AC Unit is in two different rooms. I can not run both at once. Is there something I can have done so I can run both at once? Can I switch to 440? Is there a good list of instructions for this you know of?

    Hi Kevin,
    This is just one of the reasons why I encourage getting a permit and inspections.During the plan check phase it would have been noted that according to NEC Article 230.70(A)(2) and 240.24 Service equipment or other panel boards are not allowed in residential bathrooms.
    Electrical work without a permit such as this will always be a problem if the home is to be sold, and inspections take place. What will be required will be up to your local building department. I have been on jobs where the panel is rotated 180 degrees to face into another room, just a thought.

    I renovated my basement 6 years ago (2006) in Massachusetts. I bought my home in 2004 and when I did I had the builder put in rough plumbing for a half bath. Directly behind the toilet (but approximately 1 foot to the right) is where they placed the fuse box. When I finished the basement there was no place to move the box. Is it a code violation to have the box in this half bathroom? There is no way to seperate it from the rest of the room…..especially now that it is completed. I am selling my home and I am thinking about pulling a permit after the fact. I know it can be done. Will they make me remove the bathroom?
