Final update on Victron 100/20 controller fire

Victron has been gracious enough to honor the warranty on this product, and I have no installed the replacement. Running great!

The ferrules will work fine. They are compressible and do crush. The contact area will be very good. Particularly in those vice terminals. That said, it is relatively easy to under-torque or over-torque the small terminals in the Victron 100/20, so one has to be careful. The screws are pretty weak and over-torquing will sheer the heads right off.

What probably happened the first time... what typically happens, is that not enough wire is stripped off and the person pushes insulation into the terminal contact area, which creates a bad connection. With ferrules that can't happen as the plastic shield prevents pushing the ferrule in too far.

The Victron 100/20 cannot take larger than 10 AWG. Even 10 AWG is a bit of stretch when using ferrules. Usually you have to use 12 AWG with ferrules in the Victron 100/20. But as long as you don't over-torque the screws it will be fine if you managed to stuff the ferruled 10 AWG all the way into the terminal.

At 0:47 - Pinched insulation under the terminal?

Whats the load voltage and how much can you put on it 100w 200?

If you sustain twenty amps For any amount of time, .Watch out for that fuse holder. If you don't have a temp gun make sure to just feel it. Have personally melted them.😂

With what Victron charges for their products, they could send you 10 replacements and still be profitable.

Well there's your problem, you are using wire ferrules. Do not use ferrules with wire terminal blocks that Victron uses. Use fine multi-strand tinned copper wire instead (coated in dielectric grease if used in marine salt environment) that is as large gauge that will fit inside the terminal block hole. Ferrules provide single point contact against the terminal and are not compressible to provide spring force against the terminal bolt which is essential to keep that bolt from untwisting during vibrations.
