I have just hooked up a WattNode and I cannot tell if it is reporting a reasonable power. How can I estimate the power consumption of a load?
Use one of the application notes Estimating Power for Wye Circuits or Estimating Power for Delta Circuits to help compute the estimated power of a load. Then compare the results with the output of the WattNode. If they substantially disagree, you will need to troubleshoot the WattNode installation (see the WattNode Installation Manual for troubleshooting).
