There should be no connection from these wires to ground anywhere. Use nothing smaller than 12 gauge. BE180R Requires a Neutral wire. A multi-module UPS system fed from a 3-phase, 3-wire, grounded wye supply is a separately derived system because the neutral doesn't connect to the output of the UPS modules. As with many smart home devices, this dimmer requires a 2. The leaders in visual safety - Create a Safer, Smarter Facility - Home of LabelTac & SafetyTac industrial label printer and floor marking tapes. I have a situation where there is a 480V 3-Ph 3-Wire system feeding a location with some 480V motors and controls. Terminal screws accept up to #12 AWG copper or copper clad wire. There is normally no neutral required unless you are also tapping off 120 volts between hot. Line voltage enters the first 3-way switch outlet box, light fixture is located between switch boxes. (The open-main-neutral problem will not occur for a sub-main section of circuits because there is no sub-main neutral, only the main neutral for the whole panel. If you are talking about blue and black and white wires on the fan, that is typical. Moved Permanently. I am not confident you have the right switch - the feed sounds like a three or four-way feed with the red wire, or possibly a photocell switch feed, but the switch sounds like a standard one-way (single switch controlling those lights), which has no neutral - it just interrupts the live (black) feed to turn light on and off, plus the ground to. And in the case that your home does not have neutral wires, hope is not lost! Although you are limited to only a handful of smart switches that work in a 2-wire circuit and most are dimming devices. A three-phase, three-wire (no neutral), 208 V, ABC system supplies an unbalanced wye connected load as shown in the figure below. No earth wire at fittings or switches We're in the process of buying a house and the electrical installation condition report has come back showing that there are no earth wires at fittings or switches on either the upstairs or downstairs lighting. Both of these set a limit of 5% total for both.
