Safety Tips For
Making Electrical Repairs
Electrical
codes are in place to protect you, the homeowner. These general guidelines
apply to new installations and will give you the basics of what electrical
inspectors are looking for. Be sure to check with your local electrical
inspector because local codes may vary from the list provided. In the case of
existing housing, the codes will apply if you are updating a home, and it
requires an electrical update. It is also suggested that you update if the
wiring in your home is unsafe and a danger to your family.
Electrical hazards can cause burns, shocks and electrocution
(death).
Assume that all overhead wires are energized at lethal
voltages. Never assume that a wire is safe to touch even if it is down or
appears to be insulated. Never touch a fallen overhead power line. Call the
electric utility company to report fallen electrical lines. Stay at least 10
feet (3 meters) away from overhead wires during cleanup and other activities.
If working at heights or handling long objects, survey the area before starting
work for the presence of overhead wires.
If an overhead wire falls across your vehicle while you are
driving, stay inside the vehicle and continue to drive away from the line. If
the engine stalls, do not leave your vehicle. Warn people not to touch the
vehicle or the wire. Call or ask someone to call the local electric utility
company and emergency services. Never operate electrical equipment while you
are standing in water. Never repair electrical cords or equipment unless
qualified and authorized.
Have a qualified Houston
Electrician inspect electrical equipment that has gotten wet before
energizing it. If working in damp locations, inspect electric cords and
equipment to ensure that they are in good condition and free of defects, and
use a ground-fault circuit interrupter (GFCI). Always use caution when working
near electricity.
The National
Electrical Code has some very specific rules and regulations about underground
wiring methods and points of attachment. This is a look at the highlights of
the outdoor sections of the code. Electrical wiring is often subjected to wet conditions
and all of the elements that Mother Nature can throw at them. Electrical safety
around swimming pools, hot tubs, and spas should be of extreme importance to
the homeowner. Learn what it takes to have safe outdoor electrical wiring.
Strange as it
may seem, most fatal electrical shocks happen to people who should know better.
Here are some electro-medical facts that should make you think twice before taking
chances: It's not the voltage but the
current that kills. People have been killed by 100 volts AC in the home and
with as little as 42 volts DC. The real measure of a shock's intensity lies in
the amount of current (in milliamperes) forced through the body. Any electrical
device used on a house wiring circuit can, under certain conditions, transmit a
fatal amount of current. Currents
between 100 and 200 milliamperes (0.1 ampere and 0.2 ampere) are fatal.
Anything in the neighborhood of 10 milliamperes (0.01) is capable of producing
painful to severe shock.
