Rule 36.5 (GO 128)
36.5-A
General
Supply
conductors and equipment of the following types shall be bonded in manholes and
at other locations where conductors and equipment are accessible and in
proximity to one another, and shall be grounded in accordance with Rule 36.5-C:
(1) Transformer Windings: Transformer windings not exceeding 250 volts (except those used exclusively for energizing street lighting circuits and those used exclusively for energizing signal and track circuits) shall be effectively grounded at the points specified in the following:
a)
Single
Phase Systems:
2-wire 120 volt: one conductor.
2-wire 240 volt: intermediate point
or, if not available, one conductor.
3-wire 120/240 volt: mid point.
b)
Two Phase
Systems:
3-wire 240 volt: point common to
both windings.
4-wire 120/240 volt: mid point on
one phase.
4-wire 240 volt mid points of both windings connected together.
5-wire 120/240 volt mid points of
both windings connected together.
c)
Three
Phase Systems:
3-wire Delta 120 or 240 volt: mid
point of one winding or, if not available, a point common to two windings.
3-wire and 4-wire Star 120, 208,
240, or 120/208 volt, and
3-wire T or Scott 240 volt: point common to all
windings or, if not available, one conductor.
(2) Supply Circuits 0-750 Volts: Neutral conductors of 0-750 volt supply circuits.
(3) Supply Circuits More than 750 Volts: Neutral conductors of supply circuits of more than 750 volts.
(4) Metal Sheaths, Shields and Pipes: Metal sheaths and shields of supply cables and metal pipes and conduits enclosing supply cables, except as provided by Rule 36.5-B.
(5) Metal Cases Supply Equipment: Metal cases of transformers, switches, and other supply equipment.
(6) Above-Ground Metal Enclosures: Above-ground metal enclosures in which supply conductors are terminated.
(7) Lightning Arresters.
