    I recently split a circuit to install a bypass sensor, and I learned some lessons the hard way. Make sure to double-check your wire connections! I accidentally mixed up the hot and neutral wires, which caused the whole system to short out for a while. Now I label everything before I start. Highly recommend doing that! Also, remember to have a friend help you out if you're unsure.

    • Thanks for sharing that! Labeling sounds like a great idea. I’ll definitely have someone help me, just in case.
