What is a double tap on a breaker?
A double tap occurs when your electrician attaches two wires to one specific breaker or one terminal on a breaker. Almost all breakers are designed to only handle one wire per terminal.
What is a double tapped neutral?
What Is a Double Tapped Neutral? A double tapped neutral is when more than one neutral wire is fed into a single screw (terminal) on the neutral bus bar in the main electric panel. You can see this clearly in the picture below, as there are multiple neutral wires feeding into a single screw in more than one instance in this spaghetti mess of wires.

Is it OK to double tap a circuit breaker?
It is unsafe to have double tap breakers because it may cause circuit overloads. This means that the breaker trips because it cannot handle the demand coming from two different circuits. However, some brands of circuit breakers are designed to have a double-tapped connection in your electrical system.

Can you double tap a 2 pole breaker?
When it's NOT a defect: Double tapped wiring is ok if the circuit breaker is designed for two conductors. If a circuit breaker is designed for two conductors, it will say so right on the circuit breaker, and the terminal of the circuit breaker will be designed to hold two conductors in place.
How much does it cost to fix a double tapped breaker?
A double-tapped breaker costs about $150-$250 to fix. Double-taps are a common defect in an inspection report, but it is easy to correct.
Is a double tapped breaker a fire hazard?
The problem with a double tapped breaker is that circuit breakers aren't designed to hold these two conductors together. While they might feel secure and seem to be working fine, these conductors could loosen up leading to arcing, overheating, and safety hazards, including fire.
How many breakers are allowed in a 200 amp panel?
Most 200 amp panels will have 40 breaker slots but can accept more circuits with tandem breakers. 120v single-pole breakers will use 1 breaker slot, while 240v double-pole breakers will use 2 breaker slots. Manufacturers rate their panels and limit the number of electrical circuit breakers based on that rating.
Can you put 2 wires on a Square D breaker?
It depends -- some circuit breakers are designed to accommodate two wires. If they are, though, it'll be clear that they are. For example, these Square D Homeline breakers are marked with symbols or text indicating that two conductors are allowed but only if they're both copper.
Can you have two breakers on the same circuit?
There is no valid way for two breakers to control the same circuit. Either through accident (as suggested above, poorly placed staple) or oversight (creating a direct splice between hot wires belonging to two different circuits), there is a short between the output of breaker#1 and breaker#7.
Why are 2 breakers connected?
Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there's a short circuit on either of the poles' hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC's circuit.
How much can a 20 amp breaker handle?
How many Watts can a 20-Amp breaker handle? A 20-amp breaker can support up to 2,400 watts on a single circuit. The safe maximum for a 20-amp circuit is 1,920 watts, but circuits should not be loaded to more than 80 percent of their maximum capacity.
How much does it cost to fix a circuit breaker?
Replacing a circuit breaker switch can cost between $100 and $200. For 15- to 20-amp switches, the cost averages $5 to $15 each, and 15- to 20-amp fuses cost between $5 and $10 for a pack of three. Older fuses can cost up to $70 and can be challenging to find.

Why are some breakers double?
Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there's a short circuit on either of the poles' hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC's circuit.

How to Fix Double-Tapped Breakers
The good thing about double tapped breakers is that they can be relatively easy and cheap to fix. There is more than one way to fix double tapped breakers, which means you can choose whichever method is the most comfortable and most convenient for you to do. First, you’ll need to remove the panel cover to access the breakers.
What happens if you have more than one neutral wire?
When more than one neutral wire is fed into a single screw/terminal on the neutral bus bar, the connections can become loose. When there are loose connections in your main panel from a double tapped neutral like this, they can cause overheating or arcing, which can then lead to shock, and an electrical fire.

What is a double tap?
A double tap is quite simply two electrical wires attached to the same breaker in the electrical service panel. This is a pretty common condition in homes as over the years additions and electrical changes are made. Often times this leads to someone taking a short cut and simply attaching two wires to the same breaker. Most breakers are what’s known as “single pole,” meaning they are only capable of serving one wire. Attaching a second wire exceeds that limit, which can cause overheating and an electrical fire.
What does it mean when you double tap a breaker?
Shutting off a breaker with a double tap means that power is cut off to both wires, which may be in different sections of the home. This can increase the chance for electric shock when completing home repairs by causing repair personnel to touch electric wires that they believed were not energized.
What happens if you hook up a second wire?
Attaching a second wire exceeds that limit, which can cause overheating and an electrical fire. A double tap; the black and yellow wires both terminate at the same breaker. In addition, creating a double tap can become confusing and inconvenient when it’s necessary to cut the power to a given area of the home.

Can a double tap be fixed?
The double tap is fixed, just like that. Sometimes there is no room for another breaker in the panel. A final option is the “tandem breaker.”. Tandem breakers replace an existing breaker, however the tandem breaker has two poles and two breakers, so it can accept both wires.
What is double tap in a circuit?
A double tap occurs when two wires are connected to a circuit breaker that is only designed to accept one wire. It’s considered a defect for most breakers because the two wires compressed under a one-wire connector may not be securely fastened. Some, but not all, circuit breakers manufactured by Square D and Cutler Hammer are rated to accept two wires.
