shall be used and connected to the motor frame inside the motor terminal
conduit box.
Where the ground conductor is not included with the power conductors in
the motor circuit raceway, the motor frame shall be grounded to the near-
est building steel or to the ground grid as shown on the drawings.
Suitable grounding facilities, as approved by the Engineer, shall be
furnished on motors not so equipped. The grounding facilities shall
consist of compression type ground conductor termination bolted to the
motor frame and providing a minimum of joint resistance.
The conduit system is not considered to be a grounding conductor except
for lighting fixtures. No grounding conductor shall be smaller in size
than 12 AWG unless it is a part of an approved cable assembly.
4G.4 GROUND SYSTEM RESISTANCE. All ground resistance measuremeats
shall be made with a three terminal "megger" type ground tester which
applies alternating current to the electrodes and which gives a reading
in direct current ohms. Two reference grounds shall be used and all
tests shall be made in accordance with instrument manufacturer's instruc-
tions for ground resistance testing,
Prior to connection of grounding electrodes to the grounding system the
Contractor shall obtain individual measured ground resistance data for
selected electrodes as shown on the plans. These data shall be obtained,
identified, and recorded under the supervision of the Engineer and sent
to him within 5 days.
