Find the allowable ampacity for #10 gauge HSJO six conductor cord.
Solution:
Step #1
T.400-5(A)(1) provide ampacity values for HSJO cord: 35 amperes.
Step #2
The ampacity that this table provides must be adjusted using T.400-5(A)(3) if the number of conductors that make up the cord exceeds three. Since in this case we have six conductor cord, a demand of 80% must be applied to the table’s ampacity value for this cord.
Step #3
Solve for allowable ampacity.
= Table ampacity x Table adjustment Factor
= 35 amps x 80%
= 28 amps
