Kris@Horticontrol said:I noticed some people questioning the method of only flipping the hots... Guess they haven't spent as much time as we have trying to find the most reliable way of doing it. As you know from our testing, flipping both the hot and neutral causes a larger in rush of current , which leads to a larger arch. That is why our relay supplier (we don't use that nte branded one) suggested only flipping hots, so the current can "back flow" on the neutral during the switch over. the "danger" of a "live" neutral on the unlit bulb vs. the danger of huge arching welding contacts and melting them down creating a fire hazard is a no brainer to me As long as all of the equipment is properly wired and grounded it isn't an issue.
