[Solved] IEC module wiring logic
(1/3) > >>

Hello everybody,

Still in the build of my arcade bartop cabinet, this time I am looking for a way of having a nice electric outlet at the back of the bartop. I saw many posts on forums and pages, but never a clear explanation of the logic behind it.

I intend to plug the computer, screen, leds, harddisk and everything on one power strip, inside the bartop. Then plug the powerstrip to an outlet, inside the bartop, connect the outlet to an IEC outlet and having only one IEC cable coming out of the bartop, to plug it to the wall.

In that way, I find it more clean, more easy to change, repair and nicer. Here is a little drawing for better understanding :



Sorry it is in french, so "bloc que je desire realiser" means "bloc that I would like to build", "prise mur" is the wall outlet, and "boite de derivation qui contiendra le bloc" is the box that is represented by a red square.

I have everything already, the box, the outlet, the iec module, the cables ....

Only thing, is that I don't know how to wire the IEC module to the outlet.
I read many different posts on forums, saw many images, schema, it is always different and answers barely explain the logic behind it in order to be able to do it with a different configuration.
So here I am, trying to wire my outlet (which again, will be inside the bartop, and looks like that) :



so 2 L, 2 ground, and 2 N

to my IEC module (which will go to the outside), note that it has a LED that lights when on ON






on the last picture, you can notice that the pin at the bottom right is in another color, a bit orange, while the rest are more silver, that on the same side of the switch when on ON

I also have these just in case:



So I found this image with an outlet that look (the back of it) like mine :


the green is the ground, the blue is the N and the brown is the L

however, I dont know if the ON switch is on the same side as mine, so I don't know if the wiring would be the same.....

So I am a bit lost on what to do, and how to be sure I do it correctly, thus I would like to understand the logic (I am noob in electronics but I want to learn).

Thanks for any advice and help !

Welcome aboard, Hycday.   ;D

Check out this wiki entry for a schematic of how to wire your power inlet.   :cheers:

 

The only other consideration is if you have chosen the correct fuse for your power inlet. (They usually don't come with a fuse installed.)

thank you PL1

i saw this also, but I am not sure of the following :

the schematic is when the ON is "behind" the 8 (like the second picture you posted, at the left of the front side)?

and the lamp will turn on when the switch is pressed (behind the 8 ), so the bridge to the 7 will go, and the lamp/led will turn on, is that right then ?

last question : so I have a wire from 1 to 6, then daisy chain from 6 to neutral, and I have a wire from 4 to 8, then from 7 to hot, but do I also have a wire from 8 to 7, or is this done 'internally' like from 3 to 5 ?

as for the fuse, I got the small ones, 10A, they fit in it
PL1:
There are many vendors selling this type of power inlet with different types of switches and/or lights. (LED, incandescent, etc.)

That makes it easy to make a mistake trying to provide a wiring answer for the tabs based on the physical description of the switch.

The switch can be installed facing either way, so the easiest way to tell which two terminals are 7 and 8 is to use your multimeter to check for continuity (<2 ohms) when the switch is in the "on" position, and an open when the switch is in the "off" position.

As always, ensure that the IEC cord is NOT plugged in before using your multimeter in Continuity/Ohms mode or you'll fry your meter.

BTW, if you wire it with 7 and 8 reversed, the light will be lit all the time.

Thanks for asking -- I've updated the wiki page to include this additional info.

Thanks a lot PL1 for these details.

I understand what you meant about the fact that there are no real general rules, and that is exactly why I wanted to understand how to do it and not just follow a wiring schematic.
However, with your picture and explanation I understood the logic, at least part of it.

Just this last part about the 7/8 terminals is left.
I recorded myself with the multimeter, and, with the switch on ON, when I touch the pins 6 and 7, the meter displays numbers, when I touch nothing, or the pins 7 and 8 or the pins 6 and 8, the meter stays on "1    ." :


Therefore, I assume that continuity on my module is on 6 and 7 and not on 7 and 8 ? right ?

So in my case, if I follow your schematic, I must switch 8 and 6 ?
thus, a wire from 1 to 8, then daisy chain from 8 to neutral, and I have a wire from 4 to 6, then from 7 to hot?

and you did not answer the question about the fact of wiring 6 to 7, or is this done 'internally' like from 3 to 5 ? (I am saying 6 to 7 if I stick to the fact of switching 8 and 6, otherwise if I follow your original picture, the question would be 8 to 7)

thanks again !
