Up to eight Masterpact NT or MTZ1 800 A breakers fit in one 30 inch section, which makes Power-Zone 4 compact for its rating. Breakers of the same frame size and interrupting rating are interchangeable between cells. Power-Zone 4 is switchgear to UL 1558; the similar-looking QED-6 uses the same Masterpact breakers but is a UL 891 switchboard.

The nameplate
Straight on and readable. Voltage, ratings, model, and serial in frame.
Inside

The whole unit
A wide shot plus what is around it, so we can plan the pick.
The lineup nameplate is usually on the front of the main section. Each breaker has its own nameplate on the front escutcheon. One breaker plate per frame size plus the lineup plate is enough to price it.
