Safety Switch
A safety switch is only needed if required by the
local electric utility. Some utilities require a safety switch to
be placed before the meter to allow their employees to turn off
power to the meter for servicing. Most utilities that require a
safety switch only require it for 480V services. The safety switch
is always unfused. The safety switch amp rating is the same size
or larger than the main breaker. Standard sizes are 60, 100, and
200 amps.
