FAQ

Questions engineers ask first

What is the difference between Type G-GC and Type G portable power cable?
Type G-GC includes three phase conductors, two split grounding conductors, and one insulated yellow ground-check (GC) pilot conductor for continuous ground-loop monitoring between the power centre and mobile machine. Standard Type G omits the ground-check pilot and distributes grounding conductors in the interstices.
When should I step up from Type G-GC to Type SHD-GC?
Type G-GC is an unshielded 2,000 V cable. Step up to Type SHD-GC when the circuit voltage exceeds 2,000 V (5 kV to 25 kV) or when mine regulations and fault-protection schemes at 2 kV require individual metallic braid/tape shielding over each phase core.
How are the grounding and ground-check conductors sized in Type G-GC?
The two green-insulated or bare tinned copper grounding conductors sit in two of the outer interstices and together provide at least 50 % of the cross-sectional area of one phase conductor (from 2 × 10 AWG up to 2 × 2/0 AWG). The third interstice holds the yellow-insulated ground-check conductor (10 AWG, 8 AWG or 6 AWG).
What minimum bending radius applies to Type G-GC trailing cables?
Per ICEA S-75-381 Part 6 Table 6-1, unshielded Type G-GC cables up to 2.00 in (50.8 mm) overall diameter (3 × 8 AWG through 3 × 3/0 AWG) require a minimum bending radius of 6 × OD. Sizes over 2.00 in OD (3 × 4/0 AWG through 3 × 500 kcmil) require 8 × OD.
Can Type G-GC be used in wet underground or surface mining locations?
Yes. Both the 90 °C EPR phase insulation and the two-layer reinforced thermoset CPE outer jacket are rated for 90 °C wet or dry operation, oil and chemical exposure, sunlight, and severe rock abrasion in surface and underground mines.
