category, and therefore must be treated with greater considerations as far as grounding requirements
are concerned.
Since Type B grounding requirements stipulate 5 ohms or less impedance to earth ground, things such
as soil pH, type of grounding rods, size of conductors, and ground enhancing materials must be taken
into account to achieve this goal. To verify the impedance requirements are met, a special
Earth/Ground Resistance Tester (megohmmeter) may be necessary.

If the MOTOMESH Duo 4300 Device product is attached to a light arm and the
attachment point meets the Type B grounding requirements, then the grounding stud
attachment point is not required to be used.
