I want to measure how many kilowatts or kilowatt hours are going through some of electric lines in my house. For reasons too numerous to list here I can't use a standard kill-o-watt (basically some of these appliances are hardwired and don't have plugs).
Can I use data that you get from an AC clamp meter to calculate kilowatts going through a line?
There are a whole bunch of calculations here: http://www.rapidtables.com/convert/electric/Amp_to_kW.htm
but I am not sure which one to use and if I can get all the information I need from an AC clamp meter. If I can't use an clamp meter is there anyway to measure killowatts flowing through a line?
To be clear this is what I am calling an Clamp Meter: http://www.homedepot.com/p/Commercial-Electric-Digital-Clamp-Meter-MS2002/202353289?keyword=ms2002
Clearly I am not an electrician so any help would be appreciated!
