6.7.6 Control box or panel grounding
DANGER
Electric shock
Death or serious personal injury
‐
The control box or control panel must be permanently
grounded in accordance with the National Electrical
Code/Canadian Electrical Code and local codes or
regulations.
The ground wire must be a bare copper conductor at least the same
size as the submersible drop cable wire size.
Run the ground wire as short a distance as possible and fasten it
securely to a true grounding point.
True grounding points are considered to be one of the following:
•
a grounding rod driven into the water strata
•
a steel well casing submerged into the water lower than the
pump installation depth
•
steel outlet pipes without insulating couplings.
If plastic outlet pipe and well casing are used or if a grounding wire
is required by local codes, connect a properly sized, bare copper
wire to a stud on the motor and run to the control panel.
DANGER
Explosive environment
Death or serious personal injury
‐
Do not ground to a gas supply line. Connect the
grounding wire to the ground point first and then to the
terminal in the control box or control panel.
