Are electrical panels required to be locked?
Brian Lord
A
Answer:
Hey Brian thanks for your question. Not specifically but they can be as stated in 110.26(F) for up to 1000 volts and in 110.31 for over 1000 volts. There are other locking requirements in 490.35 for over 1000 volts. Locking equipment can help keep unqualified persons from accessing equipment they shouldn't be.
