- General Product Information
PANDUIT – FOR PUBLIC USE | January 15, 2020 | P: 800-777-3300 | www.panduit.com
article 240.21(B)(1)(b) Exception (NFPA 70:2017). This rule allows a tap of no more than 10 feet on a
feeder circuit without the need for overcurrent protection.
Other local wiring codes and regulations may require use of overcurrent protection. Always follow
applicable codes and standards when installing the device. The VeriSafe AVT can be installed safely with
overcurrent protection. When installing overcurrent protection with the VeriSafe AVT, it is important to
install one overcurrent protection device for each of the six sensor leads. Overcurrent protection should
not be installed with the two green ground leads. Do not install multiple lead wires on one overcurrent
protection device in a configuration that would leave lead wire pairs electrically connected in the event
that the overcurrent protection is in the open state. Top of the Document
IS02 Will installation of VeriSafe Absence of Voltage Tester affect the short circuit current rating
(SCCR) of my equipment?
The VeriSafe Absence of Voltage Tester is suitable for use on circuits capable of delivering up to 300,000
rms symmetrical amperes at 600V or less. AVTs listed to UL 1436 are required to operate as a
galvanically isolated secondary circuit that is isolated from the circuit conductors by use of a
transformer, optical isolator, or limiting impedance, or other similar means. This is intended to reduce
the risks of both electric shock and thermal hazard. These galvanic isolation circuits allow very limited
current flow, if any, through the AVT. Top of the Document
IS03 Is the VeriSafe AVT a power circuit?
The VeriSafe AVT is not part of the current carrying power circuit. It is a measuring device to determine
the absence of voltage in the power circuit. VeriSafe AVT detects the voltage of the three-phase power
circuit, but the current from the power circuit does not flow through VeriSafe. The VeriSafe AVT is
similar to a voltmeter, testing the circuit voltage without actually being in the power circuit current
path. In the event of a short circuit fault, the short circuit current does not flow through the VeriSafe
and no short circuit current rating (SCCR) is required.
IS04 Can the VeriSafe Absence of Voltage Tester be installed on a single-phase system?
The tester is designed primarily for three-phase systems, but can also be installed on single-phase
systems. Refer to schematics in the Instruction Manual. Top of the Document
IS05 Can the VeriSafe Absence of Voltage Tester be installed on a DC system?
The tester is primarily designed for three-phase AC systems, but it can be installed on a DC power
system. When installed in a DC system, the AVT is not polarity specific. If installed on a DC system, there
are no differences in the absence of voltage test function. However, the voltage presence indicators are
designed to illuminate when AC voltage is detected. The presence of DC voltage will not be indicated.
Refer to Installation Schematics in the Instruction Manual for further details. Top of the Document
IS06 Will the VeriSafe AVT detect improper installation?
The AVT will detect lack of continuity between the two leads for each phase, and between the two
grounding leads. Installation must be performed per the installation instructions by a qualified
electrician who must verify proper installation and operation of VeriSafe as described in the Instruction
Manual. Top of the Document
