content: Binding posts like those illustrated don't accept standard 4mm banana plugs, so for most purposes you would be better off with something like this Pomona dual post:These are available fromDigikeyandMouserand are rated for up to 500V and 30A.

content: Quote from: pallav.aggarwal@gmail.com on June 09, 2016, 07:48:55 pmGetting pre-made binding posts that look like that is tricky, I've looked around before.But if you search Aliexpress/eBay for M6 Knob you will find knobs with m6 threads, both male (knob attacked to shaft) and female (knob screws onto shaft) threading is available, putting an M6 bolt, or nut into your design so you can attach your knob of choice is easier. Cross-drilling a hole through an M6 isn't too difficult if you have a drill press.Personally though, I just use inset safety banana jacks, if I need to connect a bare wire, it's a 30 second job to attach a banana plug and do it properly, or a 3 second job to use a banana-to-alligator lead and do it dodgily.

content: I have a BK Precision 8600 and wish it had regular banana jacks. I have to use cumbersome adapters to interface with the bulky binding posts on the unit. I don't understand why they use these, other than to drive sales of their proprietary cabling.

content: Yes, those BK Precision posts are really PITA!You should much more easily find 4mm banana posts that also have the same feature for directly binding a wire.

content: Thank you everyone but i was looking for the same if possible.My electronic Load Project need to sink 16 Amps current and in future would like to scale it up to 25 Amps.Do you guys think BK precision is getting it custom built for their instruments? I have see similar on many manufacturers power supply and electronics load instruments.Thanks again.Regards/Pallav

content: Thank you for your response.Reasons:- Look wise i could not see anything else better in my personal opinion.- As i have never used, assuming it will be able to handle 25Amps current- Grip will be better due to large surface area.May i kindly ask what are the disadvantage associated with these binging posts?Regards/Pallav

content: Quote from: pallav.aggarwal@gmail.com on June 10, 2016, 05:40:28 pmThat's fine.De gustibus non est disputandum.QuoteAs will many of the binding posts available from Mouser, Digikey et al. The examples given above handle 30A, as I mentioned earlier, and so do many others.QuoteMost 30A binding posts have a larger diameter than the normal 10A variety, partly to allow more grip.You don't need a huge amount of grip to securely attach a wire, anyway.QuoteSure:You can't attach 4mm banana plugs, the most common type of test lead termination in most labs.The posts are less clearly colour codedThey appear to be very difficult for individuals to source.

content: I've used these beforehttp://www.altronics.com.au/p/p9220-red-30a-600v-heavy-duty-binding-post/Not sure what is on the bk precision load as I've never been close to one.Where are you located? If you don't have any luck getting them closer to home, I could let you know how much postage would be and send them to you.
