4.1 In-wall / In-ceiling installation: 3.5” Deep Electrical Box (2, 4, or 6 gang)

Electrical Outlet Box 4” Square x 3.5” DEEP is required for HNB-A, B, or C units. See RACO (www.hubbell-raco.com) models; #255 or #256 (or equiva-

lent) for UL / NEMA rated box. You may “stack” electrical boxes or utilize appropriate Mud-ring to achieve 3.5” DEEP within the

electrical box (refer to Raco #781 or #795 at 1.25” – 1.5”). Depending upon the AHJ or local building code you may utilize a 2-gang

‘LVF’ (low voltage frame) for Class 2 wiring devices.

Mud Ring 4” square / 2-gang opening at least 1.0” or greater as needed (see Electrical Outlet box above).

Conduit EMT, rigid or flex conduit may be required, for ceiling or wall installations, to meet local building codes or authority having jurisdiction (AHJ)

requirements. NOTE: CONDUIT MUST ENTER THE E.O. BOX PER DIAGRAM (above) FOR PROPER FIT.

Speaker Wiring 16-18 AWG ‘TWISTED pair’ recommended.

Ceiling Support In-ceiling installation MUST have adequate HNB

support above the suspended ceiling grid system and needs to follow local

building codes and utilize a hanger assembly such as Erico/CADDY UL listed models 512HD or 512HDXT or equivalent.

Electrical Outlet Box Codes may require the power supply be mounted in a 4-gang standard or plenum E.O. box (RACO #943 or equivalent).
