FAQ - Electricity

Q: Is it possible for a low-tension, 120-volt wire to cause a fatal shock?
Yes! Statistics confirm that a high percentage of past electrocutions involved 120-volt circuits. In fact, death can be caused by one tenth of the current required to light a single 100-watt, 120-volt light bulb. And electricity at 120 volts is the standard in all houses, today.

Q: Can wood conduct electricity?
Yes! Contrary to a number of popular beliefs, natural wood is often a conductor. The sap flowing through tree branches enhances the conductivity of wood. Likewise, rain and snow penetrate the wood of decks and ladders, which, in turn become conductors. Metal is an excellent conductor of electricity and is often imbedded in wood ladders for structural purposes, again increasing their conductivity. Although wood can be a good insulator, it must be treated and maintained under certain specific conditions. That is why wood is no longer allowed to be used as insulation.

Q: If a violent wind knocks a TV antenna onto a conductor, can this affect the television inside the house?
Yes! As soon as it touches a conductor, the antenna provides a pathway that allows uncontrolled electricity to flow directly to the television, creating a hazardous condition.

Q: Are multiple outlets always safe?
No! A surge on the circuit can cause overuse of a multiple outlet, and lead to a fire. We recommend the use of a surge-protected power bar to avoid all possibility of an overload.
