When you get it up and running be sure to measure how many Amps the motor is pulling at its max pressure just before it cycles off. If it exceeds 25 Amps you will need to get the next size smaller pulley or risk burning up the motor. Walta

I think the Lantern power monitor can do 3 panels https://lanternpowermonitor.com/configuration/panel#panel I have one it has worked well for me. Walta

My opinion early electrical devices are unsafe designs by today’s standards. Any single failure could easily result in someone getting shocked or worse. Upgrading to a 3 pronged plug with 3 wire cord that grounds the metal parts you are likely to touch is a huge improvement. Then it takes 2...

The problem is the modern residential openers send digital data as a series of pulses and this switch is very analog. Walta

When I search on Amazon for ( 4 conductor wire 14 gauge) I see many options. I just remember when dissembled one of those pendants the strain relief was molded onto the cable. It might be a change to get the short cable out and the long one in without damaging the relief.

How long will the 14 gage wire be? Will the only 120 volt load be the opener? Maybe a light. Note you are not allowed to put the voltage control wires in the same pipe as the 120 volt wires What gauge wire do the instructions call for on the control wires. Consider using direct burie cat 5 cable...

I think the smart move is to replace the short cable with a longer cable. Every connection is a potential failure point and give that the control is going to be hanging from this cable I can’t imagine a splice that would distribute the pull evenly among the 4 conductors. Is the plan to put the...

Note the combo breaker GFI offers equipment protection at 30 mA of fault current. In your kitchen you need the life safety protection offered by the stand alone GFI at 5 mA. Walta

I don’t understand what is your point? You are really going to lower your set point to 45 when it gets very cold out so your heat pump will be more efficient? I like to think of myself as a cheapskate if you really lower your set point the colder it gets you have me beat. LOL “Cold climate heat...

To your electric meter and your homes set point it does not matter if the 10kW element or the 15-kW element gets energized. You house need X number of BTUs beyond what the heat pump is producing and the system must energize the strip heaters to get the BTUs. Both strip heaters produce 3412 BTUs...

What the AI says is both true and false. Yes 500% is possible and likely when it is 50°F outdoors. Cops under 1 are very common when it is cold outdoors with under charged and or low end equipment. Walta

The smart move is to put in the required grounded outlet. If that is simply to much work and you’re willing to bet your life that the new fixture will not have a ground fault while you are touching the metal parts of the fixture then the screw in adapter will likely work just fine. Walta

Note If you find you need /want Alexa to setup or operate the thermostat installing the Alexa app on your phone should do everything an Alexa device can do. Walta

OK what is to purpose of beam B in the load path? How much load can a 2x6 spanning 20-25 feet carry? Get out the span tables and have a look. If it is supposed support the midpoint of the joists, should it not be considerably stronger than the multiple joists it supports? Beam A looks to be a...

It is nice that the roof did not fall and crush you. Before you start adding more wood and glue to the failed mistakes of the past consider paying for a professional engineers opinion. My guess is it was built without a plan by someone who mistakenly thought they knew what they were doing. Lord...

It is pretty much impossible to “bypass” the sensors. The sensors report to the board their status with serial data. Without the correct set of pulses, you are stuck with that error. I think the after-market sensors sell for $20 or so. Walta

The contactor is a great idea mostly because I simply do not believe the low cost Chinese switch will truly break a 2 horse power motor circuit reliably before the car gets crushed.

Seems to me 120mf is too large a number to be in the circuit continuously. I don’t see a centrifugal switch that leaves us looking for some electronics that will shut down the start windings. Could there be a current relay hidden in the pressure switch. Are there more than 2 conductors don’t...

Just to be clear you want to control this “WIFI switch” via the internet so you can control it when you are near or far away or only control it when you are close enough to connect to your router...

Get the 87v it is the best! The only reason to consider different Flukes is their lower price tags. Walta
