Expert Tip #15: Rectifier Cabinet Mounting
Common Air-Cooled Rectifier Mounting Techniques:
Most air-cooled rectifier cabinets will mount on a steel pole or wood post, which is common in rural areas. Standard, air-cooled rectifier cabinets typically include a mounting channel that can be bolted to the pole or post, and the channel fits the contour of the pole or post for mounting ease.
This same cabinet configuration can be mounted to a wall or backboard instead of a pole or post. This is less common but is done in locations such as production facilities or similar.
Air-cooled rectifier cabinets can also be fitted with a mounting pedestal. This pedestal frame converts a pole or post mount cabinet to a free-standing cabinet, which is typically mounted to a concrete pad. 
Ornamental Mounting:
In more populated areas, CP rectifiers can be mounted inside a free-standing cabinet referred to as an “ornamental” or “decorative” cabinet. The standard factory cabinet is no longer required because the rectifier sub-frame mounts inside the ornamental cabinet. In addition, other components, such as a shunt panel or remote monitor can be included inside the cabinet, making for a nicer project appearance. 
Farwest designed and offers the POWERHOUSEplus line of ornamental, air-cooled cabinets, which is a multifunction cabinet solution providing an AC input breaker, a power company watt-hour meter location, and an AC convenience outlet. The cabinet provides room for a CP rectifier, shunt board and a remote monitor. This configuration provides an orderly rectifier installation.
Oil-Cooled Cabinet Mounting:
Oil-cooled cabinets are usually mounted to the ground in some fashion, typically on a concrete pad. Depending on the size of the cabinet, rectifier pads can be quite large and may require the use of a reinforcing bar or other structural support within the concrete. In some locations, a containment system may be required in the case of an unlikely transformer oil leak.
