Sounds like certain professors. Have tons of knowledge but no common sense, real world knowledge. I'm an electronic technician by...

Yes. In actual life the chances of two of them starting at the very same instant are ridiculously long odds. Even so, if they have soft...

Look at the diagram again. Two can run at the same time. If any two are running the third will not start. If two are running and...

Just use relays on the signal lines from the thermostats to the compressors. You will need Qty:3, three pole, double throw relays...

My mind goes to my trailer and it's gas appliances... Ammonia refrigerators - think RVs - nothing but a small pilot flame and a...

That's an important fact. Modern electronics power supplies use a three stage process to make the low voltage DC required by the...

I’ve got an ancient TrippLite APS2424 that produces modified sinewave, with 2x12v AGM batteries. The thing weighs a ton due to its...

skipping all the drama... buy a victron, a midnight solar, a magnum, a morningstar, a Schneider, a xtant (however you spell it) etc...

I spent the last 40 years in the telecommunications industry. Replacing one bad battery will buy you a year and then you’ll have 4 bad...

Consider also that the amount you earn per hour is nowhere near the amount of money the company has to pay to keep you employed. An...

I agree from personal experience 50 feet does not prevent ground loops. We had to watch this all the time at a power plant I use to work...

I don’t know if this is worded wrong or is naturally wrong but it’s wrong. A subpanel must derive its dirt/earth/ground from its...

One other note I thought of. If you want to replace the individual fuses with a single 250A then you'll need a thick wire gauge capable...

Personally I think you are over engineering this and that is part of why it is getting complicated. Once that remote battery unit...

That's not how electronics work. If the fuses are all in parallel and they are all the same rating then they all, nominally, blow...

This is an easy way for your friend to protect their RV from a myriad of electrical faults, including what happened to you: Progressive...
