measuring blower motor current
I've noticed that my electricity consumption has increased recently and for various reasons I suspect an HVAC squirrel cage blower motor. Although it doesn't seem excessively hot, I want to find out if it's drawing more than the rated current. It has a shielded AC cable running to it. What is the best way to measure current? Can I use a clamp meter to do this or would it make more sense to do something like measure impedance with the power off? I don't want to do any dis-assembly and I do have some knowledge of electricity.
