8.4.5 Recommended Sizes of Battery Cables and Fuses
Sizes of cables and fuses are shown in Table 8.2. Sizing is based on safety considerations
specified in UL-458, NEC-2014 and ISO-10133. Please refer to “Notes for Table 8.2” for
details.

NOTES FOR TABLE 8.2
1) Column 2 indicates the rated continuous DC input current drawn from the battery.
2) Column 3 indicates minimum NEC Ampacity for sizing of conductors. NEC Ampacity
is not less than 125% of the rated continuous DC input current (Column 2) - Refer to
NEC-2014 (National Electrical Code) - Section 215.2(A)(1)(a) for Feeder Circuits.
3) Column (4) indicates the size of external fuse in the battery circuit. It is mandatory to
install this fuse within 7” of the battery Positive terminal to protect the battery cables
against short circuit. Amp rating of the fuse is based on the following considerations:
a) Not less than the Maximum Continuous DC Input Current (Column 2)
b) Closest Standard Ampere Rating of Fuse has been used - Refer to NEC-2014
(National Electrical Code) - Section 240.6(A)
c) Where Standard Fuse Rating does not match the required Ampacity (Col-
umn 2), the next higher Standard Rating of the fuse has been used - Refer
to NEC-2014 (National Electrical Code) - Section 240.4(B)
d) Type of fuse: Fast-acting, Current Limiting, UL Class T (UL Standard 248-15)
or equivalent
4) Columns 5 to 7 indicate minimum cable conductor size that is based on the following 2
considerations. Thicker conductor out of the following 2 considerations has been chosen:
a) As per guidelines in ISO 10133 for 105°C cable insulation and cable running in free
air. Conductor size is based on:
