Question:

Does a 24v connection have to in a box

Steve Farrington

A

Answer:

Hey Steve thanks for your question. You don't say what type of 24 volt circuit it is but if it is a remote control, signaling, or power limited circuit then only specific sections of Article 300 apply as stated in 725.3. Also live parts operating at 50 volts or more must be guarded as stated in 110.27. So, no, 24 volt connections do not typically need to be made in a box.
