What types of electrical loads require surge power?
Resistive types of loads (like incandescent lamps, toaster, coffee maker, electric range, iron etc) do not require extra power to start. Their starting power is the same as their running power. Some loads like induction motors and high inertia motor driven devices will initially require a very large starting or surge power to start from rest. Once they have started moving and have attained their rated speed, their power requirement reduces to their normal running power. The surge may last up to 5 seconds. TVs and microwave ovens also require surge power for starting. The manufacturers specification of the appliances and devices indicates only the running power required. The surge power required has to be guessed at best.
