B-LINE 304811 HRTCT – Frequently Asked Questions
1) Can the B-Line 304811 HRTCT CT cabinet be installed outdoors?
Yes. The 304811 HRTCT CT enclosure carries a Type 3R degree of protection, which is the rainproof rating used for outdoor service and metering equipment, and it is UL listed. The shell is galvanized steel finished in ANSI 61 gray paint, the standard utility gray for exterior-mounted gear.
2) What are the dimensions of the B-Line 304811 HRTCT current transformer cabinet?
It measures 30 inches high, 48 inches wide and 11 inches deep, so plan the wall space and any working clearance in front of the cover around a 48 inch wide box. Weight is listed at 142.21 lb, which is a two-person lift and needs blocking or unistrut backing on stud or block wall.
3) Is this CT cabinet for single phase or three phase service?
Both. The 304811 HRTCT is rated for single phase or three phase current transformer installations, so the same cabinet works for a 1P residential-style service or a 3P commercial service entrance.
4) Does the 304811 HRTCT have a hinged door or a bolt-on cover?
Hinged. The cover swings rather than lifting off, which matters when the cabinet is 48 inches wide and mounted at height, since you are not handling a loose 48 inch panel on a ladder. Bolt-on covers are the alternative if a utility in your area requires a fully removable, sealable flat cover instead.
5) How does the B-Line 304811 HRTCT mount?
Surface mount only. It fixes to the face of the wall or to a strut rack, not recessed into it, so the full 11 inch depth projects out from the finished surface. For a flush installation you need a flush or semi-flush style CT cabinet instead.
6) Is the galvanized steel body on this CT cabinet suitable for a coastal or washdown site?
The 304811 HRTCT is galvanized steel with ANSI 61 gray paint and a 3R rainproof rating, which covers rain, sleet and snow on a normal exterior wall. It is not a stainless or non-metallic enclosure and is not rated for hose-directed washdown or corrosive marine exposure, so for salt-air or washdown duty specify a stainless Type 4X CT cabinet instead.
