greetings code lovers,
My question is, I replaced a manual motor starter switch which controls a 1/2 horsepower fan motor at a local facility. The switch was sent with the wrong size heater element. It will take about one week to get the right one from the factory. The customer wants to know if I can install a commercial grade snap switch in its place until the proper part arrives. This fan is on a 20 amp circuit breaker with other lighting loads. My question is, is this safe and legal? Does a commercial snap switch have to have a horsepower rating to be used with a motor? Is there any reason for using a manual motor starter switch besides the built-in overload? Thanks in advance.

thats a pretty good reason, isn't it?
The need for overload protection not withstanding, I believe 430-109(C) would allow a general use snap switch to be used in this application.
 
Re: manual motor starter switch

thank you augie47.
Does this mean that I must use the manual motor starter switch w/overload due to 430-32D(2) because the fan is not within sight of the switch? If the fan and switch were in sight of each other, then I could use the breaker as the overload protection and the snap switch as a disconnect? What is the meaning of the exception to 430-32D(1)? thanks.

I didn't see an exception to 430.32(D)(1)

As I see it, if its 1/2 hp permanently installed motor, it must have overload protection.
In addition, there must be a disconnecting means in sight of the motor or lockable.
