Standard Turntable Power Washer v. 4.0 The MART Corporation
5.2.4. Electricity (Input)
NOTE: You are responsible for meeting all local and national
electrical codes that apply to the power source and to the
wiring from the power source to the MART Power Washer.
Be
sure that people who are qualified and trained for the task do
all electrical installation and connections . They should meet
all local licensing requirements.
NOTE : If your washer is not equipped with a disconnect, NEC
(National Electrical Code) requires a main disconnect.
CAUTION! GROUNDING WARNING: The washer must be
grounded! Grounding provides a path of least resistance for
electric current, thus reducing the risk of electric shock during
maintenance, troubleshooting, or repair.
CAUTION! GROUNDING INSTRUCTIONS: The washer must be
connected to a grounded, metal, permanent wiring system; OR
an equipment-grounding conductor must be run with the
circuit conductors and connected to the equipment-grounding
terminal or lead on the washer.
Earthgrounding to Prevent Corrosion
The washer must be securely grounded to help prevent stray electrical fields from
causing galvanic-type corrosion. Under some circumstances, such corrosion can very
quickly cause serious structural damage to the washer (in only several months).
WARNING! Use the proper equipment-grounding circuit per
the National Electrical Code Article 250.
The Power Washer must be grounded using a copper conductor. Do NOT depend on
raceways or a conduit as an equipment ground. Install an equipment-grounding
conductor connected to the Power Washer’s ground lug in the Control Panel
and
connected to your electrical service system ground according to the National Electrical
Code Article 250. Use a conductor
EQUAL or GREATER in size to the equipment
service conductor to reduce the resistance to ground. A low-resistance path-to-ground
is required to minimize galvanic corrosion.
