Detector VS Alarm

[rbleich (Richard Bleich)]

@pmarin

An electric panel will generally have one or two covers. Panels with two covers have an outer cover (which will open to the side or upwards) and an inner cover, called a “Dead Front

I have heard this explanation from my brother-in-law, an electrician for over 40 years. Yet it still seems to conflict with the NEC definition and InterNACHI definition. What is your source?

I started a new thread…

Panelboard cover vs. Dead front

Article 100 NEC definition: Dead Front. Without live parts exposed to a person on the operating side of the equipment. NEC defines the term as an adjective, not a noun, as opposed to a “live front”. InterNACHI redefined the term “dead front” to mean the correct term for a panel board cover.
