Current through Register Vol. 51, No. 22, November 1, 2024

Section 20.50.11.03 - Contact Voltage Survey Test Results

A. Each electric company shall make an area safe after detecting a potential contact voltage condition during its contact voltage survey until the potential condition can be confirmed under §B of this regulation.

B. Each electric company shall confirm and document all contact voltage detected in its contact voltage survey using a voltmeter and a 500 ohm shunt resistor.

C. For each contact voltage measurement under §B of this regulation greater than or equal to one volt (60 Hertz Alternating Current), each electric company shall:

(1) Perform a contact voltage survey on all objects and surfaces that are capable of conducting electricity and are publicly accessible within a minimum 30 foot radius of the location of the measured contact voltage;

(2) When an electric distribution plant or an electric company-owned or-maintained streetlight is indicating contact voltage, immediately and continuously make the area safe, and use best efforts to make a permanent repair to mitigate the contact voltage as soon as possible, but not later than 45 days, however, a temporary measure to mitigate contact voltage may last longer than 45 days in extraordinary circumstances provided the area remains safe;

(3) When non-electric company property is indicating contact voltage, immediately use best efforts to make the area safe and immediately use best efforts to notify the customer or responsible person associated with the premises or the customer-owned facility of the unsafe condition and the need for the customer to make a permanent repair to mitigate contact voltage; and

(4) Maintain written records of its actions to make the area safe and to mitigate the contact voltage.
