Extension box with EMI/RFI filter

[Love4sound]

I am building an extension board with 20A load EMI/RFI dual stage filter. Previously I did a 6A board and connection was easy with crimping. This 20A version has bolt type terminals. It has two bolts and two washers in between. Just wanted to run by members here on how to finish the connection. So the input has Line, Neutral and earth terminals. Output has only L-N. so I need to wind two wires and connect earth connections at both ends. For line and neutral should I wind the wires inbetween the washers and tighten the bolt? Please find the images of the product and terminals and advise

Thanks a lot. Should I get a crimping tool or just use a cutting plier? I tried my local shops and they don’t have the crimping tool. Checked amazon and it’s 1500-2000 for the kit

If this is good enough I’ll go for it. Ritchie street is very far from my home.

Then amazon will be cheaper considering the cost of petrol now days.

I think, Cutting plier is enough upto 10sq. mm lugs.

Ok but I have ordered the crimping tool suggested above.

 

[Love4sound]

Couldn’t get from stores nearby including mercy electronics so I ordered lugs on Amazon. Please check the product and let me know if this good enough?

Cutting pliers cannot crimp tight. They cannot punch through the lug like a crimping tool. If there is a loose contact, you had it. Use proper tools.

Is the outer diameter of those screw on the EMI filter 2.5mm?

Not sure and spec sheet is not available. Anyways I have cancelled it. Managed to get exactly 6 lugs from urban company electrician. It’s fitting but slightly big. Hopefully should be good enough

That's fine. Put it in between the two washers that have come for each of those terminals

Sure. The 20A EMI filter is very big so ordered an outdoor junction box. Should arrive by Saturday.

It should be snug fit on the stud else it can become loose due to thermal cycling, overheat and melt. Lug's hole should be just 0.1 to 0.5 mm larger than the bolt.

Your previous order on Amazon said the ring dia is 5mm. That is the hole size. Perhaps too large.

Ok so the lugs I have shared in the image are not snug fit. If you can see the image they are slightly loose. So I need to take it to the shop and buy lugs after trying them on.
