pin power point which is effectively grounded through the normal household wiring.
Extension cords used with the equipment must be three-conductor and be correctly wired to
provide connection to ground. Incorrectly wired extension cords are a major cause of fatalities.
The fact that the equipment operates satisfactorily does not imply that the power is grounded and
that the installation is completely safe. For your safety, if in any doubt about the effective
grounding of the power, consult a qualified electrician.
