Hi all,

I'm in the middle of the build seen here at the moment, I have all of the large components but I'm still gathering some of the smaller items.

I have a question regarding the fuse holder, fuses and resistors. I see that the fuses are 1 amp fast blow, but what is the proper fuse holder to use? I was thinking of going to Radio Shack for these smaller parts, would these work?

Any help would be greatly appreciated as I'm clearly new to all of this. Thanks!

Yes, those parts would work.

You should not use that Estop design. Been beat to death on this forum, but... Purposefully faulting a breaker is not proper practice.

... Purposefully faulting a breaker is not proper practice.

It's not like it's being used as a primary power toggle. Each component in that schematic has a dedicated switch. In an emergency, which seldom occurs, all power to all components can be shut off with one button. Seems useful for its purpose.

Confusing the electrical novice OP with such a fine point does him no good. In fact, confusion is the last thing he needs from HBT. The schematic is sound.

Argh. It's precisely because the OP is new to high power electronics that small details like that should be raised. That is why this community is great, we all help each other.

This is an issue which has been done to death. Just because there are still bad schematics floating around does not make it the right thing to do.

The correct way to do an E-stop is with a suitably rated contactor to cut the master power to the panel. You can still drive it through a standard mushroom switch and the contactors themselves are very cheap.

There are certainly other ways to skin that cat. To simply dismiss the OP's schematic as bad or not proper practice provides only confusion. A link to a good schematic with proper practices might be more helpful to the OP.

I'll toss in an example of a main power latching circuit, which is part of a larger 120v RIMS/CFC controller circuit I had been working up.

Audiophool, thanks for your quick response to my question and thanks to raouliii for providing me with a possible alternative e-stop design.
