PowerUp Products recommends the
practice of using a Drip Loop when installing wiring into any electrical
equipment. A Drip Loop is a mechanical strain relief formed by bending an extra
length of wire into a, hand sized, downward loop just before it enters into the
equipment’s cabinet. This functions to
prevent moisture from entering the cabinet by directing any water splash or
condensation that collects on the wire to run away from the equipment and drip
famous American Legend of June 1752 has Benjamin Franklin capturing electricity
with a kite and a key in a glass jar.
Records of his various writings show that he was quite aware of the
danger in mixing electricity with water.
That's why he also figured out a way to protect people, buildings, and
ships from it with a lightning rod.
Following on his work the U.S. Department of Labor, Occupational Safety
& Health Administration (OSHA) has published some regulations specifically
to ensure safety around electrical equipment, a small excerpt of which follows.
(Standards - 29 CFR) PART 1910 –
DESIGN SAFETY STANDARDS FOR ELECTRICAL SYSTEMS
Enclosures for damp or wet locations;
Cabinets, fittings, and boxes; Cabinets, cutout boxes,
fittings, boxes, and
panel board enclosures in damp or wet locations shall be
installed so as to
prevent moisture or water from entering and accumulating within
In wet locations the enclosures shall be weatherproof.
Modern solid-state electronics are increasingly rugged and reliable,
intelligent electrical wiring practices still need to be followed. By providing electronic equipment protection
against water damage, short-circuits, corrosion and other dangers can be easily
