Your air conditioner must have a dedicated circuit so you can have peace of mind knowing that it’s less likely to trip and that your electrical system will work more efficiently. It’s also important to do this if you’re looking to install an AC system for the first time or your home has an outdated electrical system.
Can an air conditioner be plugged into a regular outlet?
If a larger air conditioning unit is plugged into a standard outlet, it will likely trip your breaker during start-up. Even if a large unit can be powered with a standard outlet, prolonged usage can result in damage to the air conditioner or your breaker, so a proper outlet and dedicated circuit are crucial.
Are AC units on their own circuit?
Most window air conditioner units are 110/120 volts. These air conditioner units that require 7 or more amps to operate will need their own dedicated circuits.If you do not have a dedicated air conditioner circuit, a professional electrician will need to install one for you.
Does a portable AC unit need its own circuit?
Consider the following before you install any type of air conditioner: With a few exceptions, most window air conditioners will require their own dedicated circuit so they don’t overload an existing room circuit.You should also make allowances for the height of your ceiling and the size of your windows and doorways.
What kind of outlet do you need for an air conditioner?
For most homes, 30-amp or 40-amp 240/250-volt circuits are typical for a central air conditioner. For portable 240/250-volt plug-in air conditioners like those that fit into windows, 20-amp circuits are typical. In either case, the circuit must be dedicated to the air conditioner unit.
Is it OK to plug an air conditioner into an extension cord?
Normal extension cords can’t handle as much electricity as permanent wiring, so if you use one to plug in your AC unit, the cord can overheat and start a fire. The same goes for attaching extension cords to other large appliances, like refrigerators or freezers.
Does a portable AC need a special outlet?
When you rent a portable AC unit, you’ll need to ensure that you have the proper outlet and electricity setup. There are two parts to the plug type: voltage and amperage. Most residential rooms have circuits rated for a total of 15 amps of electricity, and many units have 125V/15A plugs that can be used in most homes.
Can a window air conditioner be plugged into a power strip?
It is not safe to plug an AC unit into a conventional power strip as it can cause electrical fires to break out. Instead, you can use surge protectors. These devices look and function just like a power strip but with added protection against power surges, which can damage your unit.
Can I use aircon without breaker?
The answer is yes, you need a separate circuit breaker for your aircon. And according to the PEC, the load capacity should be 30A.
Can I use a surge protector for my air conditioner?
It is not recommended to use ANY surge protector on a AC unit. Most newer AC units have a built in surge protector.
Why do aircon need breakers?
Here’s the most important thing to know: your AC circuit breaker is a safety switch that protects your equipment from damage by turning off the power when an overload is detected. It also protects your safety since overloaded circuits can result in a fire.
Are AC and furnace on same breaker?

What kind of extension cord can I use for an air conditioner?
Extension cords for air conditioners are usually a minimum of 14 gauge, which is considered medium duty.
Gauge
- 16-gauge cords can handle up to 10 amps for up to 100 feet.
- 14-gauge cords can handle 10 – 15 amps for up to 50 feet.
- 12-gauge cords can handle 10 – 15 amps from 50 – 100 feet.
Why does my aircon trip the power?
Well, an air conditioner usually trips the breaker because it’s pulling in more amps than the breaker is rated for. That is, if you have a 20-amp breaker and the AC pulls 30 amps, the breaker trips. That’s why breakers trip: to protect you from over currents that can damage equipment and cause fires (yikes).
Do you need circuit breaker for 1hp aircon?
Answer: 20 Amp circuit breaker is enough for a 1 HP motor air conditioner. Why 20 Amp? Because 8.1 AMP is far from the 80% demand factor of a 15 Amp circuit breaker. It is better to go 20 Amp for 1 HP air conditioner.
