I purchased Hoffman's power cord - fuse assembly to use in my Plexi/800 build. Could anyone verify that I am wiring it correctly. I have attached a drawing showing the way I think it should be done. Would like confirmation from someone more knowledgeable than I am to okay it.
Thanks

Don't wire it like that! You'll blow the fuse as soon as you flip the power switch. Look at this instead...

Thank you sluckey. I will reflect your drawing in the schematic and build.
Thanks

Do you see what you did wrong? :think1:
You had the 2 PT primary wires going to the on/off switch, + to 1 side of the power switch, - to the other side of the power switch. So flip the power switch and bang! direct short.

I see now what I did wrong. The reason I posted it was that it did not look right and I knew that others on this forum could see the problem in short order. I appreciate the knowledge and the willingness of people to help those of us that have no training in electronics. I just do this because I really enjoy building something that I think sounds pretty good when I finish it. I am learning slowly but don't have nearly the knowledge that many in the forum have. It is nice to be able to get their help.
Thanks

Take a look at the close up photo of the fuse assembly IEC in the Hoffman catalog. Both the front and back side of the plug is actually labeled, so hopefully that should be helpful to you.
With respect, Tubenit

Just another illustration of what Sluckey already did.

I have looked and looked at the photo of the fuse assembly and my eyes are no longer able to pick out detail that fine. I will take your word for it that there is something there. I appreciate the layouts that both you and sluckey provided. Those I could see and comprehend.
Thanks

Nothing too complicated going on if you look at the back and compared that to the front
There's Neutral and Hot and ground
Instead of the hot being a direct contact front to back, it is routed through a fuse first and then out the back

There is nothing hard about it at all. I purchased it to simplify the building of the amp I am working on which it will certainly do. I am in the middle of trying to layout a sluckey inspired plexi/800 amp with two tone stacks, overdrive and inboard active effect circuitry. I probably could have figured out what I had done wrong myself but I was at a point where I couldn't see the forest for the trees and needed and asked for a little help which forum members kindly provided.
I am also trying to confirm my understanding of your relay power supply in a relay circuit and determining which jack to use with a single button footswitch fed through a two conductor wire and whether I have wired the circuit correctly. I have used the Dumble 12 volt relay power supply in the past and yours is much easier and less time consuming to use.
I will attach the layout I drew in case you have a minute where you can review it to see if it is correct? I know it has been talked about on the forum but not with the pictures I need to comprehend it.
Thanks
Mike

I merged our replies about the relay into your other post
