Should a furnace fan run all the time?

Furnace fans are designed to run all the time, so there’s no need to worry about it failing prematurely. Much of a furnace fan’s wear and tear comes from the starts and stops of the motor; keeping it running can eliminate this type of stress.

Some electric leaf blowers use a battery and are cordless but most use a long power cord, which can make it a little difficult to use. Gas blowers release smoke, a negative that leaf blowers do not have.

What’s the difference between full load amps and running load amps?

FLA: Full-Load Amps: Amount of amperage drawn when motor is working at rated horsepower. RLA: Running-Load-Amps: Same as FLA. This amperage draw is approximately 6 x FLA of the rated motor for six to eight seconds.

What wire is needed for furnace?

It’s going to completely depend on the unit that’s being installed, but commonly it’ll be 30-60 amp with 10-4 AWG wire.
