50 Most Common NEC Violations

Greetings all,I still here folks say that it's legal from time to time. (#14 switch legs on a 20 amp ckt) Heard it the other day as a matter of fact just in passing conversation. I've had to all it out a couple of times but it's a rare thing.

The one thing that I see day to day is that panels have holes in the panel or in the dead front cover not properly covered. Bear in mind I do a lot of occupancy type inspections so I look at a lot of existing stuff.

Yes but the only branch circuit that you can tap is located in 210.19(A)(3) and (A)(4) for cooking appliances. As a general rule 240.4(D)(3) limits 14 AWG Copper conductors to being protected by a maximum overcurrent protective device of 15 amps.

You can't tap a branch circuit for switch legs for example and use 14 AWG on a 20 amp circuit for the travelers or switch legs which has been a common violation.
