SafeSide thru-door voltage indicators provide electrical
safety information while the panel doors are safely closed.
This “one-size-fits-all” solution detects 3-phase AC or DC
voltage from 40-750VAC/30-1000VDC. The encapsulated
construction and redundant circuit design means rugged
reliability. SafeSide products are available with flashing
LEDs (R-3W) and non-flashing LEDs (R-3W-SR).
Keeping personnel away from live voltage is foundational to
electrical safety. Electrical safety demands a precise answer
to the question 'Is voltage present?'. Thru-door voltage
indicators provide visibility of voltage from outside the
enclosure without exposing personnel to voltage.
Workers performing mechanical LOTO must isolate
electrical energy. An externally-mounted voltage detector
provides a means to check voltage inside an electrical
panel. Without a voltage indicator, a mechanic performing
mechanical LOTO would be required to work in tandem with
an electrician using a voltmeter to physically verify voltage
inside an electrical panel. In this case, the electrician is
exposed to voltage. With thru-door voltage detectors, the
mechanic can verify zero electrical energy without any
exposure to voltage.
Voltage is the common denominator in an electrical accident
or an arc flash; no voltage means no accident, no arc flash.
While performing electrical LOTO with a thru-door voltage
detector installed, the electrician can pre-check the internal
voltage state without opening the enclosure. Next, the
electrician should replicate a zero voltage reading with his
voltmeter as per NFPA 70e 120.1(5). This low-cost,
redundant voltage-verification task reduces arc flash risk
and increases electrical safety for workers.

Warning: Verify an electrical conductor has been de-energized using an adequately rated
voltage detector before working on it. Follow appropriate Energy Control (Lockout/Tagout)
procedures as per OSHA Subpart S; the current edition of NFPA 70E; and the current
edition of CSA Z462.
