Question:
Is twisting conductors prior to installing the wire nut violating code?
Gregory Slack
A
Answer:
The NEC does not have specific rules about twisting conductors at pressure connectors so we use 110.3(B). If the twist on connector manufacturer states that twisting is not permitted, or if it is required - that is mandatory. Some suggest that pre-twisting is acceptable but not necessary.
