The manual for the EG4 12k/18k/24k hybrid air conditioner shows a power disconnect on the AC line and another one on the solar panel input. They require a sign to be posted on the air conditioner that warns you to turn off both power sources before working on the unit. I don't like this even a little bit. If a future service person doesn't understand this sign or if the sign gets damaged by weathering then someone is going to get hurt.
Is anyone aware of a four pole safety switch that's rated for 120 AC as well as 400-600 volts DC? I want to turn everything off from a single switch. It must be weatherproof so that I can mount it near the compressor unit.
