From what I understand about the issues with a double tap are:
- Multiple wires under 1 lug could work loose.
- Multiple devices on one breaker could cause overheating and or overload.
A local electritian just told me that you can legally splice into the wires running to a breaker rather than double tapping them.
Wouldn’t this still pose the same concern of multiple devices on one breaker, and therefore require to be fixed.
