Double-Tapped Breakers: It is Bad and there is a Simple Fix!
The most common defect a home inspector finds during a home inspection or 4-point inspection is double-tapped breakers. They are a hazard but they have a simple fix to resolving them. In this article, we will address some common questions about double-tapped breakers.
1. What are double-tapped breakers?
A double-tapped breaker is basically two wires under one circuit breaker that is designed for one wire. The issue with double tapping is you could technically have a loose connection or an overloaded breaker since the breaker is not designed for two wires. A loose connection can potentially spark or arc.
2. How do you tell if a breaker is double-tapped?
Square D and Cutler-Hammer both manufacture breakers that are rated to accept two wires (double taps). When two wires are allowed a tiny graphic of two wires will be visible at the front or side of the breaker.
3. Are double-tapped breakers allowed?
It’s generally not allowed and can be a fire hazard under certain conditions.
4. How much does it cost to fix a double tapped breaker?
A double–tapped breaker costs about $150-$250 to fix.
5. Do I need an electrician to replace a circuit breaker?
Do not attempt to remove the cover to the main breaker; this should only be accessed by a certified electrician or a qualified contractor.
6. How to fix a double-tapped circuit breaker?
If you have a double-tapped breaker in your electrical panel, which means two wires are connected to the same breaker, it is important to address the issue as it can be a safety hazard. Here are the steps to repair a double-tapped breaker:
- Turn off the power to the breaker by switching it to the off position.
- Use a voltage tester to confirm that there is no power to the breaker.
- Remove the wires from the breaker.
- Install a new circuit breaker that is appropriately sized for the wires that were connected to the old breaker.
- Connect each wire to its own designated terminal on the new breaker.
- Tighten the terminal screws to ensure a secure connection.
- Turn the power back on and test the circuit to make sure it is working properly.
It is important to note that if you are not comfortable working with electrical systems, it is best to hire a licensed electrician to perform this repair. Working with electricity can be dangerous and should only be attempted by those with proper training and experience.
