Re: [RC] [RC] Freezing and tank heaters - Sisu West Ranch
The instructions for many items state that no extension cords should be
used. This is a result of manufacturers trying to minimize lawsuits.
There are a few considerations with extension cord use outdoors:
1. Is the cord properly grounded with a GFCI? Lots of cords have the
round safety ground prong cut off. Some old properties do not have proper
grounds on outlets. I have one of those in my garage, 3 holes but the
third is not hooked up. If in doubt you can purchase plug in outlet
testers that will tell you.
2. Is the cord protected from mechanical damage. Running a cord on
the ground, or up in trees, or whatever for long times often produces
situations where the insulation is cut. Also remember extension cords are
not designed to be immersed in water for long times. Cut or worn
insulation produces shocks, and fires
3. Is the cord of thick enough wire to handle the power required, and the
length of run.
If a high wattage device is run on an extension cord that is to
small, the voltage at the device will be reduced. If the device has an
electric motor it can burn out from the low voltage. Note that this gets
worse as the cord gets longer. An airconditioner pluged in with a 6' 14
guage cord will run fine, but with the same cord 100' long it will burn
out. If one were to run a big tank heater from a 100' cord you would need
a 12 gauge cord.
Particularly if a cord is run inside or in burnable
material it can get hot and start fires, unless it is of adequate size.
The cheap 18 gauge cords used for lamps in a house fall into this
catagory.
My bottom line is: Install an outlet
following the electrical codes right by the stock tank. If you can't do
that, purchase and industrial strength, or contractor grade extension cord
(heavier insulation). For short runs, purchase a 14 guage cord. For
longer runs purchase a 12 guage cord. Then save your pennies, and get a
proper outlet installed before next winter.
