11-11. Selecting Extension Cord (Use Shortest Cord Possible)
A. Cord Lengths For 120 Volt Loads
Use GFCI protection when operating auxiliary equipment. If unit does not have GFCI receptacles, use GFCI-protected extension
cord. Do not use GFCI receptacles to power life support equipment.
Current
(Amperes) Load (Watts)
5 600
7 840
10 1200
15 1800
20 2400
25 3000
30 3600
35 4200
40 4800
45 5400
50 6000
*Conductor size is based on maximum 2% voltage drop.
B. Cord Lengths For 240 Volt Loads
Use GFCI protection when operating auxiliary equipment. If unit does not have GFCI receptacles, use GFCI-protected extension
cord. Do not use GFCI receptacles to power life support equipment.
