This makes the lighting protection system electrically safe. (Everything conductive must remain safe to touch)

Alternatively plant highly invasive giant bamboo close to the house within a few years you will have eco lighting rods that explode when...

You would save a ton with one them if yours is using that much power. Ours is low consumption right now because we have no...

I bought the 65 gallon Rheem heat pump model from home depot to replace a traditional unit. Along with the fed tax credit our local...

Sometimes you do get exponential decay. Once you lose dielectric isolation you are pretty much done for. That said, there are AC...

Ideally you use Type-x everywhere in a room with higher fire risk. How much you want to replace just gets down to practicality. An extra...

My panels are roof mounted, East and West. And I am surrounded by trees. This is why I require more panels than most people would.

Well, it could have been a contributor to the "house burned down" thread; initially the cells had been installed without a separator...

Easiest approach for small generators is a separate chargeverter. It won't give you AC coupling but you can use whatever is available.

Thanks to the mods for moving this. Thanks to everyone for the info and ideas. @HalfBaked thank you for the info and encouragement...

The lug and the fuse should be directly adjacent, remove those washers between them. Also is there a fuse holder or is all the force on...

117 yesterday, 114 today, my panels are beyond dirty... Jeez. @B-Mod is still top gun.

Double layer of type-x 5/8" drywall is likely better than cement board. It has an actual fire rating where cement board doesn't. You...

You need both the BMS and the fuse for different reasons. We are in agreement on the OP's situation given the information available...

Correct, however there are also 70V MEGA fuses rated at 2.5kA (littelfuse sf51). But Class-T is the way to go 20 kA@125VDC.

It wasn't the plastic that likely caused the OP's fire, it was the plasma arc that was caused by a fault greater than the interrupting...

Those fuses are rated to interrupt 2,000A at 58VDC maximum. A bolted fault with parallel strings could exceed that rating, which is...

I used to have a some of those cable for a PBX system-- BRI cards needed them. We used the label maker to mark each end and the middle...

2 GND, 4CAN H, 5CAN L. 1,3,6,7, and 8 are the pins for parallelling signals. 1,3,6,7, and 8 also control the signal for synchronizing...

My biggest concern here isn't exactly just explicitly cross over cables - what happens if a pin goes bad in a standard cable? This...
