Yes. The 364811 RTCT current transformer cabinet is a Type 3R enclosure, which is the rainproof outdoor rating used for utility metering and CT cabinets on exterior walls. It is UL listed and built from galvanized steel with an ANSI 61 gray painted finish, so it holds up on an outdoor service wall.

The cabinet measures 36 inches high, 48 inches wide, and 11 inches deep. Lay out at least that much clear wall area plus working clearance in front of it before you set anchors. It surface mounts, so the full 11 inch depth projects off the wall face rather than sitting in the wall.

Both. The 364811 RTCT is rated for single phase or three phase current transformer installations, so the same enclosure covers a 1P residential-style service and a 3P commercial service. The CTs and metering hardware themselves are separate items and are not part of the enclosure.

The enclosure is built from 12 gauge steel, galvanized, with an ANSI 61 gray painted finish over it. Twelve gauge is the heavy end of what you see in metering enclosures, which is why the empty cabinet runs 200 pounds. For a utility-sealed service enclosure on an exterior wall, that gauge plus the galvanized base under the paint is what resists dents and corrosion over the life of the service.

Yes, a 3R enclosure can be used indoors. Type 3R protects against falling rain and sleet from outside, so it more than covers a dry indoor mechanical or electrical room. Where it is not the right pick is a washdown area or anywhere subject to hose-directed water or heavy dust; those call for a 4, 4X, or 12 rated enclosure instead.

The finish is ANSI 61 gray, the standard light gray used across switchgear, panelboards, and metering equipment, so it lines up visually with most utility and distribution equipment already on the wall. It is painted over galvanized steel rather than bare galv.
