Double-tapped breaker in the panel

Symptoms

• An electrician or inspector flagged a 'double tap' in your panel
• Two wires visibly land under one breaker screw
• Panel may show signs of heat near that breaker

Likely causes

• CommonA previous DIY or unlicensed additionAdding a circuit without adding a new breaker slot is a common shortcut that isn't code-compliant on most breakers.
• PossibleA panel that's full with no open slotsSomeone may have doubled up because there was no room left, rather than adding a subpanel or tandem breaker.
• PossibleA breaker swapped in that isn't rated for double connectionsOnly certain breaker models are listed for two wires per terminal; using a standard single-wire breaker for two wires is not compliant.

What to do

1. Do not attempt to open the panel cover or touch breaker terminals yourself.
2. If you were told this by an inspector, get a copy of the report noting which breaker is affected.
3. Avoid adding more load to that circuit until it's corrected.
4. Have a licensed electrician evaluate whether a tandem breaker rated for double connections can be used, or if a new circuit is needed.
5. Ask about whether your panel has room for additional single circuits or needs a subpanel.
6. Get the correction done before selling a home or closing out a permit, since double taps are a very common inspection failure.

When to call a pro

This is licensed-electrician work every time; double-tapped breakers need to be corrected with proper tandem breakers or added circuits, not DIY rewiring.
