The disruption of power for substantial lengths of time can occur at any time
due to hurricanes, earthquakes, fires, snowfall and other natural calamities.
Having emergency backup power in such situations is not only essential for
hospitals and commercial establishments but also in homes to run critical
appliances like lights, refrigerators, heaters and medical equipment.
There are basically two types of generators that can be used in an emergency:
portable and permanent standby generators. The main difference between the two
is their output power and price.
In times of emergencies, portable generators provide the most economical way of
supplying back up power. Appliances are directly plugged into the generator
using the recommended extension cord or alternatively are connected to the home
wiring system using a transfer switch. The generators come with an electric
start or a pull start and loaded with many other features including the GFCI
receptacles.
