Product Identity
The Wiegmann A121804 is a NEMA 1 rated carbon steel enclosure designed for indoor line protection and circuit breaker housing. It suits electricians and facility managers who need a wall mounted cabinet for general purpose electrical distribution.
Cover and Finish
The solid gray cover is secured by clamps and finished with ANSI 61 powder coating for corrosion resistance. A 16 gauge steel body and 3.88 in usable opening depth provide rigid protection while the hinged cover allows quick access to mounted devices during maintenance.
Installation Notes
Pre drilled mounting holes support direct wall attachment without additional brackets. The clamps require firm hand pressure to seat the gasket evenly; uneven torque can leave gaps that compromise the NEMA 1 seal. Plan cable entry around the 12 in by 18 in footprint to avoid interference with internal components.

Questions about this item
How often does the ANSI 61 powder-coated finish need touch-up to maintain corrosion resistance?
The ANSI 61 powder-coated finish is designed for long-term protection and typically does not require scheduled touch-up under normal indoor conditions.
What limits continuous operation inside the 16 ga carbon steel enclosure?
The usable opening depth of 3.88 in limits the size of components that can be installed, which in turn determines the maximum heat load the enclosure can dissipate passively.
Does the clamp-closure design affect heat buildup or noise when the enclosure runs all day?
The solid cover with clamp closure seals the enclosure, so heat buildup depends on internal component load and the 4 in depth, while noise is limited to any installed devices since the enclosure itself has no moving parts.
