Grace Engineered Products introduce UL-approved control panel utility receptacle

The Grace Engineered Products Inside-Outlet GFCI control panel utility receptacle is now UL approved for NEMA 4X applications. The Inside-Outlet GFCI employs a unique design by combining both an external and an internal control panel GFCI receptacle into one assembly. Designed to mount on the outside of a NEMA 4X electrical enclosures and maintain the 4X rating when the housing cover is closed. This increases safety and saves time by making the GFCI TEST/RESET functions available to maintenance personnel from the outside of the control panel. By installing an external Inside-Outlet, a separate internal utility receptacle no longer needs to be wired inside the panel. Internal control panel utility receptacles have been the industry standard.  In 2002, the NFPA 79 Electrical Standard for Industrial Machinery mandated that control panel utility outlets have GFCI protection.  Furthermore, utility receptacles mounted externally to the enclosure, needed to be covered to maintain the NEMA rating when not in use (NFPA 79, 16.1.1(6) & 16.1.2).  

Moreover, the electrical safety (NFPA 70e) factors combined with the GFCI requirement have changed the application of the simple control panel utility receptacle.  For example, a GFCI can only be proven effective when its TEST/RESET function is performed monthly under live power.  Unfortunately, opening a control panel (NFPA 70e) requires personnel to don protective clothing, which turns a simple 30 second TEST into a 30 minute task. The perfect solution is for maintenance personnel to operate the GFCI TEST/RESET function from the outside of the enclosure with the Inside-Outlet.

The Inside-Outlet is available with optional circuit breakers or class CC fuse holder and is UL recognized, CSA and CE certified.
