What is better for a ground system - THW or THWN?
(OP)
All i find on the two is this:
THW (5) 75¡C 167¡F 90¡C 194¡F
DRY & WET LOCATIONS SPECIAL APPL. WITHIN ELECTRIC DISCHARGE LIGHTING EQUIPMENT LIMITED TO 1000 OPEN-CIRCUIT VOLTS OR LESS, (SIZE 14-8 ONLY AS PERMITTED IN SECTION 410-31).
MOISTURE AND HEAT-RESISTANT THERMOPLASTIC
THWN (5) 75¡C 167¡F DRY AND WET LOCATIONS
Is there a real benefit of one over the other with regard to buried ground system?
