You don't want your freezer breaker to trip while you are away for the weekend and spoil all your frozen food. The dedicated circuit will be sized so breaker will only trip because of some truly dangerous situation. If you are sharing the circuit, some load could inadvertently cause the breaker to trip. For example, if you had a refrigerator and separate freezer on the same circuit. They might run just fine for a while, but then they both decide to turn on their compressors at the same time causing an over-current situation and cause breaker to trip. Naturally this will occur at the worst possible time.

No, a sump pump should be its own circuit and although it's not code, you should also have your freezer on it's own circuit. If they were on the same circuit it would most likely trip the breaker or blow the fuse. This could result in a wet basement and the food in the freezer thawing out!


Does a fire alarm control panel need a dedicated branch circuit?

Under the NFPA Fire Alarm Code, the control panel must have its own dedicated circuit, the circuit must be labeled "Fire Alarm Circuit" and the handle of the circuit breaker must be colored red. Other rules apply in jurisdictions that adopt other standards, or for other types of fire alarms. For example, under New Hampshire Fire Code, you are PROHIBITED from installing self-contained smoke alarms on a dedicated circuit.

What is a dedicated circuit?

A "dedicated" circuit is one to which only one device is or can be connected; therefore the circuit is "dedicated" to the device. A NON dedicated circuit will therefore be one to which multiple devices can connect, such as the wall outlets in your home. Multiple wall outlets are connected to a common circuit breaker, making that an example of a non-dedicated circuit.


Can you plug your 115 volt freezer into a standard outlet?

A freezer would usually have a dedicated circuit because you don't want another device on circuit that could trip breaker and you might be out a whole bunch of money in spoiled food. So you can do it, but you may be at risk. You can buy an alarm that will sound if power is lost.

What is a dedicated outlet?

A dedicated outlet is a single circuit from a single or double pole breaker to a specific outlet or receptacle for a single specific device or appliance. An example of this would be a circuit for a refrigerator, microwave, dryer, range, etc..This is typically referred to as a "dedicated circuit". A dedicated circuit usually is supplying power to only one or perhaps two receptacles, such as a computer station. An example in your home under current code is your washing machine is required to be on a dedicated circuit. Dedicated receptacle circuits may be either 15 or 20 amp.A dedicated circuit is just what it sounds like. I'ts a circuit dedicated to one particular device. Most receptacle (you may call them outlet's) circuits will power several outlets. A dedicated circuit will power only one specific outlet or appliance. Some examples would be a refrigerator, a garbage disposal, or a microwave.
