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!
What kind of PDU are you using? Many PDUs have network management features, where you can track current for individual outlets and able to disable them if you exceed max amperage.
Therefore, you don't even need a energy meter like kill-a-watt, as most professional grade PDUs will have inbuilt feature, which are more advanced than consumer grade energy meters.
