Grinding & Polishing
It is important that the operator understands the electrical requirements for
using extension cords. The length of extension cord should be limited to the
electric
supply limitations and should never exceed 100ft in length. In addition, you
should only use (3) three conductor cords on the single-phase machines. Make
sure that any extension cord used is in good condition. Disconnect the power
source and replace or repair damaged cords and plugs before starting the
machine.
When using an extension cord, be sure to use a cord heavy enough to carry the
current the machine will draw. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. See Section 3.0 for the
table showing the correct size and type of conductor to use, depending on cord
length
and nameplate ampere rating. If in doubt, use the next heavier gauge. As the
gauge number decreases, the cord thickness increases.
When a machine is used with any extension cord, be sure to use plugs and
receptacles rated for proper voltage and amperage as prescribed by the
National Electric Code. Make sure that all extension cords are wired the same,
matching wire colors and that the ground wire (green) is secured in its proper
position.
