Approximate Starting Power Requirements
•
Incandescent lights and appliances such as irons and hot plates,
which use a resistive-type heating element, require the same wattage
to start and run as is stated on their nameplates.
•
Fluorescent and mercury lamps require 1.2–2 times their stated watt-
age to start.
•
Electrical motors and many types of electrical tools often require a
large starting current. The amount of starting current depends on the
type of motor and its use.
•
Most electrical tools require 1.2–3 times their stated wattage for start-
ing.
•
Loads such as submersible pumps and air compressors require a
very large force to start. They need as much as 3–5 times the wattage
stated on the nameplate in order to start.
If the wattage is not given for a particular tool or appliance, it can be
calculated by multiplying its voltage and amperage requirements:
Single Phase: VOLTS x AMPS = WATTS
Three Phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS
