-20- G0548 2 HP Dust Collector

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 22)

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

23. Ensure that each machine is continuously

grounded to the grounding terminal in your elec-

tric service panel.
