Minimum Gauge For Cord Sets - DeWalt DCD780 Instruction Manual

• These chargers are not intended for any uses other than
charging D WALT rechargeable batteries. Any other uses
E
may result in risk of fire, electric shock or electrocution.
• Do not expose the charger to rain or snow.
• Pull by the plug rather than the cord when disconnecting
the charger. This will reduce the risk of damage to the electric
plug and cord.
• Make sure that the cord is located so that it will not
be stepped on, tripped over or otherwise subjected to
damage or stress.
• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in risk
of fire, electric shock or electrocution.
• When operating a charger outdoors, always provide a dry
location and use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
• An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that is,
16 gauge has more capacity than 18 gauge. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size. The following table shows the correct size to
use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The lower the gauge number,
the heavier the cord.

• Do not place any object on top of the charger or place the
charger on a soft surface that might block the ventilation
slots and result in excessive internal heat. Place the
charger in a position away from any heat source. The charger
is ventilated through slots in the top and the bottom of the
housing.
• Do not operate the charger with a damaged cord or plug.
• Do not operate the charger if it has received a sharp
blow, been dropped or otherwise damaged in any way.
Take it to an authorized service center.
• Do not disassemble the charger; take it to an authorized
service center when service or repair is required. Incorrect
reassembly may result in a risk of electric shock, electrocution or
fire.
• Disconnect the charger from the outlet before attempting
any cleaning. This will reduce the risk of electric shock.
Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard 120V
household electrical power. Do not attempt to use it
