Wiegmann RHC303012 Electrical Enclosure
This Wiegmann RHC303012 is a carbon-steel electrical enclosure rated NEMA 3R for outdoor or indoor wall mounting. It suits installers who need a lockable, painted steel cabinet for circuit breakers or line protection gear. The grey finish resists corrosion in exposed locations. It is not for applications that demand a higher NEMA rating or stainless-steel construction.
Installation and common issues
The enclosure mounts on external plates and uses a hinged cover secured by a quarter-turn latch with a hasp and staple for padlocking. A 14 ga steel body keeps weight manageable for two-person handling. The usable opening depth is 11.88 in, so verify that internal components and wiring bend radii fit before final mounting. Misalignment of the latch or insufficient clearance for the hinged swing are the typical installation problems.
Capacity and headroom
The interior accepts a 31LA19 panel within a 30 in by 30 in footprint and 12 in overall depth. This volume comfortably houses standard breaker arrays and terminal blocks for medium-sized control circuits. It runs out of space when large contactors, deep transformers or extensive cable trunking exceed the usable depth or panel area. Plan the layout early to avoid rework.

Questions about this item
How can I confirm the 1/4-turn latch and padlock hasp are engaging properly after mounting the 30 in H by 30 in W enclosure?
Close the hinged cover, rotate each 1/4-turn latch until it seats firmly, then snap a padlock through the hasp and staple; the solid gray cover should sit flush with the 14 ga carbon-steel body and the interior panel 31LA19 should not rattle when the door is shaken.
What ships with the RHC303012 enclosure and what must I source separately?
The box includes the 30 in H, 12 in D, 30 in W carbon-steel enclosure with hinged solid cover, 1/4-turn latches, padlock hasp and staple, external mounting plates, and interior panel 31LA19; you must supply the padlock, mounting hardware for the wall, and any internal DIN rails or terminal blocks.
Which RHC series size should I choose if I need a 30 in wide by 30 in high enclosure with 12 in depth?
Select the RHC303012 — its model number encodes 30 in height, 30 in width, and 12 in depth, giving a usable opening depth of 11.88 in and a 14 ga painted gray body that meets CSA, cULus and UL Listed standards.
