PORTABLE POWER CABLE (QPMU)
GENERAL
This category covers portable power cable constructed and Listed for use in accordance with Article 400 of ANSI/NFPA 70, ?National Electrical Code? (NEC). Portable power cable consists of either a single insulated conductor or two or more insulated conductors, with or without grounding conductors, with an overall fiber reinforced jacket. The insulation and jacket are thermoset on Types G, G-GC and W, and thermoplastic elastomer on Type PPE.
This cable is used to supply power to mobile equipment and machinery and is rated 2000 V, 90?C (194?F) dry, and 60?C (140?F) where exposed to oil.
For cable so marked, ratings of 60?C (140?F), 75?C (167?F), or 90?C (194?F) ?wet? are also assigned. The term ?wet? indicates that the cable is acceptable for immersion in water. Cable that has been investigated for use where exposed to the direct rays of the sun is marked ?Sunlight Resistant? or ?Sun Res.?
Portable power cable employs flexible stranded copper conductors in a size range of 12 AWG to 500 kcmil, except for single conductor Type W and single conductor Type PPE which employs flexible stranded copper conductors in sizes 12 AWG to 1000 kcmil. Ampacities for portable power cable can be found in Table 400.5(B) of the NEC.
Type G ? Contains 2 - 6 circuit conductors and a grounding conductor. The grounding
conductor is either bare or covered with a green-colored braid or tape, and may either be a single
conductor or be sectioned into two or more parts.
Type G-GC ? Same as Type G except that the cable also contains one, 10 AWG or larger,
yellow insulated conductor which is used as a ground check.
Type W ? Contains 1 - 6 circuit conductors and may or may not contain a grounding conductor.
If included, the grounding conductor is fully insulated.
Type PPE ? Contains 1 - 6 circuit conductors and may or may not contain a grounding
conductor. If included, the grounding conductor is fully insulated.
