GamaTech Pressure Switch for Water Pump and Air Pump, Digital Adjustable Pressure Controller, 220V, 0-230 Psi,1/2" Male Npt

GamaTech Pressure Switch for Water Pump and Air Pump, Digital Adjustable Pressure Controller, 220V, 0-230 Psi,1/2" Male Npt

Q: If the pump is shut off due to low pressure how can it be restarted?

Turn the power off for a moment then back on

Q: I have a 2hp pump, can you recommend a relay?

Assuming that's a 220 volt pump 2 hp at 85% efficiency is about 8 amps. A 10 amp DPDT 8 pin relay is very common. They come with wiring diagrams usually.

Q: Is this sutable for 12 gauge wire?

It’s been 3 months now since installation with no problems ! I Replaced a Merrill mechanical pressure switch which had the pump and power lines enclosed within it ! Along with one of the reviews that suggested plumbing reduction fittings, I had to add a Junction Box for the electrical wiring to house the 220 volt line and the line from the pump. I set the pressures for Low 55 # and Hi at 70 #. Will post in summer how it handles water pressure with the lawn irrigation.

Q: What is the correct wiring of the unit? Since no mention of the color coding is available. A diagram w/colors would be helpful.

Only color that matters is the green/yellow wire is ground. Other 2 are your 2 hot lines (110, 115, 120V) each leg. They are labeled on the back for power in, and switched power out.
