Electrical connections
All electrical connections must
be done by a qualified electrician in compliance
with all relevant codes and ordinances. Failure
to comply may result in serious injury.
The JDC-500B Dust Collector is rated at 115-volt
only, and is provided with a 5-15P plug designed for
use on a circuit with a
grounded outlet
that looks like
the one pictured in
A
, Figure 6-1.
Before connecting to power source, be sure switch
is in
off
position.
It is recommended that the unit be connected to a
dedicated minimum 15 amp circuit with circuit
breaker or time-
delay fuse marked “D”.
Local
codes take precedence over recommendations.

GROUNDING INSTRUCTIONS
1. All Grounded, Cord-connected Tools:
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding
plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary,
do not connect the equipment-grounding conductor
to a live terminal.
Check
with
a
qualified
electrician or service pe
r
sonnel if the grounding
instructions are not completely understood, or if
in doubt as to whether the tool is properly
grounded. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating less than
150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in
A,
Figure
6-1. An adapter, shown in
B
, may be used to
connect this plug to a 2-pole receptacle as shown in
B
if a properly grounded outlet is not available. The
temporary adapter should be used only until a
properly grounded outlet can be installed by a
qualified electrician.
This adapter is not permitted in
Canada.
The green-colored rigid ear, lug, and the
like, extending from the adapter must be connected
to a permanent ground such as a properly grounded
outlet box.

Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
receptacle. If an extension cord becomes necessary,
be sure it is heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.
Table 1 shows recommended size to use depending
on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
