What is the maximum conductor length allowable on a TVSS EBA and EMA Surge Suppressors?

Issue:
Are there any wire length restrictions when installing the TVSS EMA and EBA Surge suppressors?

Product Line:
Surge suppressors

Environment:
TVSS EBA, TVSS EMA

Cause:
Installation

Resolution:
To obtain the maximum system performance, locate the device as close to the circuit being addressed as possible to minimize the interconnecting wiring length. For every foot of wire length, approximately 160 Volts (6 kV / 3 kA, 8/20
microsecond) is added to the suppressed voltage. The Voltage Protection Rating (VPR) is located on the device nameplate and is measured six inches from the enclosure sidewall, according to UL® 1449 test standards.
