HOW to build a Digital Electric Monitor Volts, Amps, KWH, PF, Hertz for your Generator 

Geez, if I keep watching this channel I'm going to go broke. I'm going to have to build a few of these. A couple for myself and some to give to my friends with generators. Actually, you could use this anywhere you want to find out how much power is being used by a device or appliance. Basically, it's a different version of the Kill A Watt meter. Yeah, the Kill A Watt would be cheaper but what fun would it be to just buy something already made? Plus the Kill A Watt is limited to 15 amps. Hmm, I wonder how far the inductor can be from the meter before the readings become unreliable? Guess I'll have to try and see since there was no mention in the product descriptions. Projects like this keep my retired hands and mind busy. Thanks Gavin!

Could you make a video showing how to make this same device with a 240v 4 wire setup. I have my generator hook to my house and would like to see the load as I flip breakers so I dont over do the generator. You would think they make something like this pre fab but havent seen it so far

Any chance you could make a video with 10/4 wire and the 30 amp twist lock?

Yes my brother 🙌🙏

sae process for a 4 prong 30a setup?

Could this be used with a 50 Amp system? If so, what changes need to be done? Thanks, awesome video!

I hope this isn’t a dumb question, but does this work for 220v from the generator? I will be sending 220v to my house and would like to monitor total wattage my home is pulling from the generator.

Thanks So Much Sir, this answered my question in the other vid u made. This is a professional looking device you made.

Can I do it the same with 120

Hi Gavin Did you make the video for the 50 amp 240 volt double meter box yet. I would like to build one and list the parts you used to and keep up the good work on videos very informative Thank you

Thanks Gavin for the inspiration. I built two, 120 volt 20 amp using 12 gauge wire with regular house hold plug and a 120 volt 30 amp using 10 gauge wire with a L5-30 plug for my EU3000is generator. I agree with another poster about spending money for some of your projects. It's fun!

Can you show how to do a 4 prung twist lock?

Thanks Gavin, we appreciate all the information in making the meters. I made mine about 6 weeks ago. I noticed you didn’t put a link for the locking plug connectors, so that you can get the credit. Thanks again my friend. Have a great 👍 day.

Can you just install one of these in the rv to see what’s coming in?

Thank you for sharing this important information listening from Bangs Texas

Have you install a hour meter on a generator?

Gavin I have a 4 wire 30 amp outlet and want a digital monitor for a 4 wire any videos??

So for checking 240 volt 50 amp you would just double that correct? Or do you use different digital gauges ?

Do you know of a digital monitor that will work with the 50A feed? (Need two CTs)

Very Great instructional video

Have you ever thought about building an adaptor for those DC plugs on generators? They're usually unregulated. I wonder if it would make sense to build a small voltage regular, to charge a solar generator for example. I assume it would be more efficient to pull from the DC plug rather than plug a dc converter in the AC outlet?

GAVIN how would you wire this if you have the L14-30 male and female ends.I see you are using a three prong type.Do I use some type of adapter or does this have to be wired a different way?

Gavin which plugs do I use my cord has 4 prongs, if I wanted to test my meter on a small 110 heat gun how would I do it?

Thanks for the video! Very Informative and helpful !

Got it. Thank you, Sir. A T Burke

Once again keep up the great videos!

What tool did you use to cut the holes in the junction boxes? Jigsaw?

Hey what do you think about this meter it’s Wi-Fi WiFi Smart Energy Monitor Switch Meter, Compatible with Alexa Google Home, Remote Control with Smart Life/Tuya App, Din Rail Tester Current Voltage Amperage Power Meter AC 110-230V 60A Multimeter

great video thanks

If you're running 30amp 2540 volt do you need to run 2 monitors or can you run 2 hot wires through 1 transformer?

Please take a look at the video at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZdQcM4w8IDQ.html and let me know if example B will work for a 4 wire set up.

I noticed that on another’s video of making one of these they put the sensor on the neutral (white) wire and yours is on the hot (black) wire. His worked also at least in the video. Does it matter? Thanks!!

Great!

So if I'm trying to use a 30 amp 4 prong plug and connector how will the wiring be different?

@Gavin's Garage will this work for 220v?

What’s the 50 amp option?

Gavin ,you will find that if you strip your wires longer out of the shield they are a lot easier to work with and you should use cable clamps on the box. Just a suggestion. Nice way to see the outputs on olde generators . Thank you.

Hey man What size wire do you recommend using to connect to the meter ?

Great tool!!

Superb tutorial!
