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 12 )
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 dust collec-
tor frame with a ground screw as shown in
Figure
13. Ensure that each machine is continuously
grounded to the grounding terminal in your elec-
tric service panel.
