IV Wiring Methods <br /> <br />692.31 Wiring Systems. <br /> <br />All raceway and cable wiring methods included in Chapter <br />3 of this Code and other wiring systems and fittings <br />specifically intended and identified for use with fuel cell <br />systems shall be permitted. Where wiring devices with <br />integral enclosures are used, sufficient length of cable shall <br />be provided to facilitate replacement. <br /> <br />V Grounding <br /> <br />692.41 System Grounding. <br /> <br />For a fuel cell system output circuit, one conductor of a 2- <br />wire system rated over 50 volts and a neutral conductor of a <br />3-wire system shall be solidly grounded by either <br />692.41 (A) or (B). <br /> <br />(A) Stand-Alone Systems. Grounding and bonding shall be <br />in accordance with 250.30. <br /> <br />(B) Other Than Stand-Alone Systems. <br /> <br />(1) Two-Wire Systems. One conductor shall be <br />terminated at the grounded circuit conductor terminal of <br />the premises wiring system. <br />(2) Three-Wire Systems. The neutral conductor shall be <br />terminated at the grounded circuit conductor terminal of <br />the premises wiring system. <br /> <br />692.44 Equipment Grounding Conductor. <br /> <br />A separate equipment-grounding conductor shall be <br />installed. <br /> <br />692.45 Size of Equipment Grounding Conductor. <br /> <br />The equipment-grounding conductor shall be sized in <br />accordance with 250.122. <br /> <br />692.47 Grounding Electrode System. <br /> <br />91 <br /> <br /> <br />
