Q: How should I ground the dust collection system in my home workshop?
Should the grounding wire be connected to each machine or just the collector
itself? .
A: A: The idea behind grounding a dust collector is to provide a
low-resistance path for static electricity to travel to the earth. The
motion of dust and air through the pipes can cause substantial electric
charges to build up, especially if you're using plastic pipe. Depending on
the situation, grounding the dust collector itself may be enough. But it may
not. Let the presence or absence of static build up on pipes and machines be
your guide. The safest approach is to provide bare-wire grounding from all
woodworking machines, through the inside of the dust pipe and to the
grounded chassis of the dust collector. The circuit is completed through the
ground pin of the outlet powering the system. This provides a path for the
static electricity to travel safely and harmlessly to the earth.
