Reduce Arc Flash Risk: The ChekVolt(TM) Non Contact Enclosure Voltage Portal
An Electrical Safety Innovation
[Davenport, IA: November 15, 2006] - Designed to reduce arc flash risks and increase electrical safety by providing maintenance personnel a no-touch voltage portal on the outside of metallic electrical enclosures. The ChekVolt(TM) interface, installed on an electrical panel, allows maintenance personnel to use a non-contact voltage detector 'pen' to check line voltage before and after they open the main disconnect. The ability to pre-verify electrical isolation before opening a panel puts an additional safety measure between electricians and hazardous voltage.
Maintenance people carry non-contact voltage detector 'pens' to quickly verify the presence of voltage in a conductor. These devices beep or flash in the presence of voltage. The ChekVolt(TM) simply extends the line voltage from the main disconnect (or other voltage source) through a wire into an encapsulated non-metallic assembly fastened to the enclosure exterior. For a low cost reliable installation, the single point ChekVolt(TM) R-1A has 6' leads, mounts into a 0.50" (13mm) drilled hole, and can be ordered with a full line of bright yellow nameplates.
Non-contact voltage detectors typically operate from 50/90-1000VAC, which allow users to apply ChekVolt(TM) to single or 3-phase AC power systems. Optional bright yellow nameplates remind personnel to pre-verify every voltage point before accessing the panel interior. Nameplates offered include; various power system graphics or generic single-phase/3-phase nameplates. ChekVolt(TM) is a UL listed 600V device and rated for use in Nema 4/4X/12 environment.

Grace Engineered Products also offers the VoltageVision® thru-door voltage indicator. The VoltageVision® (R-3W) Power Warning Alert is a 30mm pushbutton type device hardwired into the load side of the main disconnect. Redundant flashing LED's provide external indication of voltage inside electrical system enclosures. The R-3W is cost effective and easily installed. Its inherent reliability reduces electrocution risks, because it is hardwired to the voltage source and enhances LOTO procedures. The R-3W is "one-size-fits-all", and operates on 3-Phase AC/DC voltage from 40-750VAC/30-1000VDC. The R-3W is C-UL-US Nema 4X listed. Product Information:
