One of the most common electrical panel issues we come across are double-tapped breakers. A double-tap is when 2 wires are connected to a single pole. Electrical codes actually allow a certain number of double tapped breakers in an electrical panel. However, these connections can cause issues, and Home inspection associations recommend these connections be corrected.
 
This week's tip discusses why double-taps are an issue and how it can be fixed. Though some of you out there have various levels of knowledge about doing electrical work, we always recommend a licensed Electrician for all electrical repairs.
What is the problem?
Most panel breakers are only designed for single-wire connections (an exception is Square D breakers that have connections for 2 wires per breaker). The photo to the left shows a double-tapped breaker.
 
When 2 wires are compressed together at a breaker, one of the wires may not have as good of a connection as the other. This could result in arcing and potentially a fire.
How is it fixed?
The easiest fix is to remove the 2 wires and connect them to a third wire (called a "pigtail") with a wire nut, and connecting the third wire into the breaker. The photo to the left is a pigtail connection.
 
Another potential fix is to add another breaker to the panel, if there is room for it. This may be a better fix if the reason for the double tap was to avoid the additional work of adding a breaker in the first place, which may be over-stressing the circuit. A licensed Electrician can assess which fix is best for your situation.
We hope these tips have been helpful. Feel free to share it with anyone you think may benefit from it.
