Yes, it is recommended to keep both the AC breaker and furnace breaker on, especially during the respective seasons when they are in use. This ensures that the units are powered and can function properly when needed.

Would replacing an old 15 amp breaker stop the air conditioner and fan from throwing the breaker?

It is possible that replacing the old 15 amp breaker with a new one could resolve the issue of the air conditioner and fan causing the breaker to trip. However, it's also important to ensure that the electrical load from the air conditioner and fan is not exceeding the capacity of the circuit. If the problem persists after replacing the breaker, it may be necessary to consult with an electrician to assess the electrical system.


Is a 40 amp circuit breaker ok for a 30 amp air conditioner?

No, it is not recommended to have a circuit breaker with a higher amperage rating than the device it is protecting. In this case, you should use a 30 amp circuit breaker for a 30 amp air conditioner to ensure proper protection from overcurrent.


Can a 40 amp breaker not a 4 amp breaker be used to replace a 35 amp breaker for ac unit?

No, it is not recommended to replace a 35 amp breaker with a 40 amp breaker for an AC unit. Breakers are designed to protect the circuit and the equipment, so using a higher rated breaker can lead to overheating and potential damage. It is best to use the correct amperage rated breaker for the equipment.


What is the wire size for a 35 amp breaker to a ac unit?

You will need to use #8 wire.


Do you need to change your circuit breaker if you plug in a 230 volt window ac?

Yes, you may need to change your circuit breaker to one that can handle the higher voltage required for a 230 volt window AC unit. It's important to have a circuit breaker that is compatible with the voltage and amperage requirements of the appliance to ensure proper function and safety.

Where is the ac circuit breaker?

It's in the basement. Turn on the light switch behind the dryer, walk past the furnace, stay to the left of the water heater, and you'll eventually see the breaker box on the wall in front of you. For heaven's sake, do be careful.


Want a wiring diagram from ac condenser to furnace?

I think you mean from the furnace to the ac unit as the ac unit does not power anything, so here is the low voltage wiring schematic from furnace to ac unit.

Do you have to purchase a new furnace to get central AC or can central AC be added with an existing furnace using the existing duct work?

My parents did it with existing ductwork.


How do you check the breaker on the outside ac unit?

Even though the A/C unit is outside, the breaker for it will be in the entrance panel box inside your home. It should be clearly marked.


Heat pump Or gas furnace and AC unit which system to install?

Your location matters. If in Florida heat pump in more northern climes furnace & ac.


How do you know if the AC breaker matches the AC unit starting demand load?

Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.


Can a 4 amp breaker be used to replace a 35 amp breaker for ac unit?

NO!


Do AC units have a breaker inside the unit?

No


Why does a new AC in a new house throw the outside circuit breaker once a week?

If the breaker only trips once a week you may have a bad breaker or the breaker may not be large enough for your A/C unit. You should also have an electrician look for any loose connections from the unit to the breaker panel. (It is not uncommon to have a bad breaker)


What happens if you use an ac circuit breaker instead of dc breaker?

A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.


What do you do when your air conditioner trips the breaker when it kicks on?

Try adding a cercuit breaker right on the AC.
