Do I need to plug my snow thrower to GFCI outlet?
I think your question is about safely using your snow blower with a non-GFI protected outlet. As a rule of thumb, any appliance used outdoors should be plugged into a GFI outlet. In your case specifically, I think you will find that your snow blower handles and controls are well insulated electrically from the source voltage and motor. The case is probably all plastic. The risk of shock is very low, but possible if you were handling the base unit for some reason. The proper answer would then be to always use a GFI protected power source for all items used outdoors.
