I am a home inspector and often see double tapped breakers in panels. My working knowledge of this is the following:
1. Square D is the only manufacturer that designs breakers to support 2 wire connections.
2. The rated load from both circuits cannot exceed 80% of the breaker rating.
3. Double-tapping increases the risk of nuisance trips (mainly due to violation of Item 2).
4. Double-tapping is generally looked upon as a deficiency.
I hope to get some clarification because occassionally an argument develops when I call this a defect. What other things should I be aware of?
Thanks in advance for anyones help.
