Be sure that you extend the bare copper wire
down all branches of the system. do not forget
to connect the wires to each other with wire nuts
when two branches meet at a “y” or “t” connec-
tion.
Ensure that the entire system is grounded. if using
plastic blast gates to direct air flow, the grounding
wire must be jumped (
figure 26) around the
blast gate without interruption to the grounding
system.

We also recommend wrapping the outside of all
plastic ducts with bare copper wire to ground the
outside of the system against static electrical build
up. Wire connections at y’s and t’s should be
made with wire nuts.
Attach the bare ground wire to each stationary
woodworking machine and attach the canister
dust collector frame with a ground screw as
shown in
figure 27. Ensure that each machine is
continuously grounded to the grounding terminal
in your electric service panel.
always guard against
static electrical build up
by grounding all dust col-
lection lines.
