Square D HC3291TSHR – Frequently Asked Questions

1) Is this I-Line trim for a surface mount or flush mount panelboard?
Surface mount. The HC3291TSHR trim is configured for surface-mounted I-Line panelboards, where the box is fastened to the wall face rather than recessed. If your enclosure is recessed into the wall, a surface trim will not sit correctly and you need a flush trim instead.
2) What voltage is this Square D I-Line trim rated for, and can it be used on a DC panelboard?
The HCJ trim front carries a 600VAC, 250VDC maximum rating, so it is suitable on both AC and DC I-Line distribution systems. That covers typical 480Y/277V and 208Y/120V commercial three-phase services as well as DC distribution up to 250 volts.
3) Is this trim suitable for an outdoor or washdown electrical room?
No. The enclosure rating is NEMA type 1, which is indoor use only, for dry, clean electrical rooms and mechanical spaces. For outdoor, damp, or hosedown locations you need a NEMA 3R, 4, or 12 rated I-Line enclosure and trim instead.
4) Is the Square D HC3291TSHR trim UL listed for an inspected commercial job?
It is cULus listed, meaning compliance to both UL and CSA standards, under UL File E33139, and it is also CE certified. That covers it for inspected commercial and industrial power distribution work in the US and Canada.
5) Will this HCJ trim fit any I-Line panelboard, or do I need to match the box?
Match it to the box. A panelboard trim is sized and drilled to one specific enclosure height, width, and hinge orientation, so the HC3291TSHR is a replacement for the I-Line assembly it was built for, a surface box with right-hand hinging. Pull the catalog number off the existing panelboard box or interior and confirm it calls for this trim before ordering. A trim that is close but not matched will not line up with the box flange or the breaker openings.
6) What does door-in-door mean on a panelboard trim, and why would I spec it?
Door-in-door means there is a hinged dead front inside the outer door. Open the outer door and you reach the breaker handles through the inner dead front without unbolting or removing the full trim panel. Electricians switching or resetting breakers in an occupied building get access without exposing live bus. On the HC3291TSHR the assembly is hinged right, so the door swings from the right side of the panel.
7) What is the difference between this Square D I-Line trim and the ABB RLP front trim cover?
They are not interchangeable. The HC3291TSHR is built for Square D I-Line panelboards, which use a bolt-on plug-in bus design, and the ABB unit is a front trim cover for that brand's RLP series panelboards. Panelboard trims are brand and series specific, so pick the trim that matches the panel already on the wall.
8) What is the difference between the Square D HC3291TSHR trim and an ABB RLP front trim cover?
Both are dead front trims that close off a panelboard interior, but they serve different panel families. The Square D HC3291TSHR is an I-Line series trim front in a door-in-door, surface-mount configuration with hinged-right access, rated 600VAC, and the ABB AF-55FD is a front trim cover for the ABB RLP series. Choose the trim that matches the manufacturer and series of the panelboard box already installed.
9) Where is the Square D I-Line HCJ trim front made?
Country of origin is the United States. That matters on public and federally funded projects with domestic sourcing requirements, so it is worth noting on the submittal.
10) Does the trim arrive assembled or do I have to build it up on site?
It ships factory assembled and ready to install, so the door, hinges, and dead front come as one unit. Field labor is limited to hanging it on the panelboard box and securing it.
