high-voltage compartment only after the door to the low-voltage compartment has
been opened. There shall be one or more additional fastening devices that must be
removed before the high-voltage door can be opened. The low-voltage
compartment door shall be a flat panel design, side hinged, and the compartment
door shall have three-point latching with a handle provided for a locking device.
Hinge pins and associated barrels shall be constructed of corrosion-resistant
material,passivated AISI Type 304 or the equivalent. The front sill of the
compartment shall be removable to allow the transformer to be rolled or skidded
into position over conduit studs.
