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 29) 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 to the dust | |
collector frame with a ground screw as shown in | |
Figure 30. Ensure that each machine is continu- | |
ously grounded to the grounding terminal in your | |
electric service panel. |
