The kil-a-watt that I have says it should only be used for 100-120v. I want to check my total wattage being used on my 240v items, but I can't seem to find a product that can do that.

Plus, it wouldn't even fit, because my 240v does't use standard plugs, obviously. I have a NEMA 240v twist-lock connected to a PDU.

Thanks!
