First I'll give you some background. My daughter has an interior design business, she bought a building that has two sections the front is the office/design area, the back is the warehouse/receiving area.
I installed Caseta switches in the office area.
The warehouse has 2 3-way lighting circuits with high bay LED lights, one lighting circuit is 6.8 amps 120volt and the other is 8.9 amps 120volts. The amperage of these circuits is to high for Lutron switches to operate directly. I am thinking that if I connected a SPST relay between the switches and the lights, This would allow me to use the Caseta switches.
The switches would only be energizing and the relay coil which will be low current. The energized coil would close the NO contact which would handle the higher current. Flip either switch the other direction and the circuit is open the coil is denergized and the lights shut off just like it would in any other 3-way circuit. Just want to run this by somebody else incase there is any problem I didn't see with this. Thanks
