RECOMMENDED MINIMUM AWG SIZE FOR
EXTENSION CORDS FOR BATTERY CHARGERS
AC Input rating amperes* AWG size of cord
Equal to or
greater than
but less
than
Length of cord, feet (meter)
25 (7.5) 50 (15) 100 (30) 150 (45)
0 2 18 18 18 16
2 3 18 18 16 14
3 4 18 18 16 14
* If the input rating of a battery charger is given in
watts rather than in amperes, the corresponding
ampere rating is to be determined by dividing
the wattage rating by the voltage rating —for
example:
1,250 watts
= 10 amperes
125 volts
9. Do not operate battery charger with damaged
cord or plug-replace them immediately.
10. Do not operate battery charger if it has received
