Portable Power Meter
These plug-in power meters are low cost and great for checking appliances etc. You can move them around, leaving connected to each appliance or a group of appliances for a week or so and see where all the power money is going. |
Switchboard mounted Portable Power Meter
In the process of collecting up the info I noticed that our power-factor on some equipment is not as good as it could be and we may be paying quite a bit more for power than we need to. I will have to put a meter on the hot water and do some more research. Note: You need an electrician to install this type of switchboard mounted power meter. |
