Frequently Asked Questions
Is it all right to
replace a fuse or circuit breaker with a
larger one to prevent them from blowing
In most cases the answer is no. They are
designed to blow at certain levels to protect
equipment and for fire safety.
What is the difference between a
floodlight and a spotlight?
The floodlight will have a broader light
pattern, while a spotlight will focus on
a more narrow area.
What is a polarized plug?
One prong is bigger than the other. This
feature is designed to make sure that a
110-volt plug is never put into a socket
that is not a 110-volt outlet.
Will a three-pronged plug adapter
protect me against electrical shock when
I use it in a two-prong receptacle?
Only if the wall plate screw is grounded.
I am installing a ceiling fan; do
I need a special electrical box?
Yes, special fan support boxes are designed
for hanging heavy fixtures-up to about 50
pounds. Since a ceiling fan moves, these
boxes are good for about a 35-pound ceiling
What is a ground fault interrupter?
It's a safety device that shuts off the
power if a wire in an outlet develops a
leak that could electrocute someone. This
hazard is so serious that the National Electrical
Code requires all new homes be equipped
with them in the bathroom, kitchen, workroom,
outdoor, basement, garage and swimming pool
I’ve always heard that fuses
are better than circuit breakers. Is this
still true today?
While at one time this was true, it’s
not so true today. Fuses blow faster than
a circuit breaker on an overload condition.
While a breaker may take a few seconds longer,
it still protects your home’s wiring
from overheating very efficiently. Unfortunately,
fuses have not been installed regularly
in homes since 1950, the birth of the circuit
breaker panel. So any fuse panels still
in existence in homes for the main service
are over 50 years in age. The equipment’s
failure is eminent.
