If you’re in a split phase, common in homes in North America, the wire harness should be:
- black into L1
- red into L2
- blue and white and the neutral bus bar
The Gen 2 Vue Energy Monitor pulls only 2 watts when connected. You can terminate the wire harness into any size of breaker you have. You can use a breaker larger (or smaller) than 15A to power the Gen 2. Just make sure that 1. black is seeing L1 and red is seeing L2, 2. they’re in a split phase, and 3. blue and white are going into the neutral bus bar.
If you are going to tap into an occupied breaker larger than 15A (i.e. pigtailing), then the short black 14 gauge wire we supply in our accessories kit should not be used (it is only rated for 15A) and you will need to use the appropriate gauge wire for the tap. If the breaker is unoccupied then there is no need to use the wiretaps as you can install the wire directly into the breaker.

Remember: the wire harness is also responsible for half of the accuracy on the Gen 2, it reads voltage and powers the device, so it needs to be properly installed. Please follow the install guide and terminate the wires accordingly to the number of phases of power in your system!”
