Yes all of them fit. (They are all "CAT1", i.e. without the shrouds around the plug tips.)

The length really depends on where you want to use the leads, and how things are arranged on your bench. My power supplies sit on a shelf just above the bench, and I mainly use 0.5 m leads -- long enough to reach down onto the bench and a bit to either side, but no excess length to avoid clutter on the bench. Sometimes I need longer leads, but I don't think I have any that are longer than 1 m.

If you want to order only one pair of leads for starters, I would go with 1 meter length.

I don't have a bench yet. I mostly don't have anything. I'm slowly starting to gather tools that are 'a must' (like bench power supply, stereoscopic microscope and hot air station). I will not be able to buy them all at once, since I need to spare enough money for all of them. So I decided to first start with bench power supply so I can at least 'feel' how it looks like when you 'hunt' for a short on some faulty motherboard.

So...for the lenght of the test leads I guess it all depends how high above your bench you hold your power supply. I guess its somewhere like...30-40 cm above the bench (table)?
I don't know. I really have no experience. Somehow I think 1m is too short, but then again I might be wrong since I really have no clue.

(could you make a photo of your bench and bench power supply so I can visually see how it looks like?)


EDIT:
I googled the voltage for CAT 1 cables and I found this:

^ did I understand correctly that with CAT 1 cable I can measure voltage up to 150v while current being up to 5A ? (or is it much less than that, for both voltage and current)?

For what it's worth, a picture of my "bench" is attached below. For perspective, I assume this is at the bottom end of the scale of bench sizes you will find among forum members. 8) In fact, my whole bench is a shelf: one of my trusty Ivar bookshelves from IKEA into which I installed two 60 cm deep boards as a desktop.

The shelf with the power supplies, scope and frequency generator sits 40 cm above the desk. That's a height which gives me good visibility of the desk, and also puts the equipment on the shelf at a comfortable height (easy to reach and see). I also get bright and glare-free lighting from an LED strip attached below that shelf.

As you can see, the bench was meant to be twice as wide, but the left half has been taken over by old arcade and computer stuff for now. I might reclaim it as a bench if I get more serious about electronics... Not shown is the large (!) cupboard full of materials, old projects, working and non-working equipment, more old computers, radio stuff, etc.. Electronics and adjacent hobbies have a tendency to eat up space over time...

Regarding your question about CAT1 cables: "Extra-low voltage", i.e. voltage which is considered safe to the touch under all circumstances, is typically specified as < 50V AC or < 120V DC. So the 30V output of your power supply (or even +- 30V if you combine two supplies into a dual supply) is still very safely within that range.

Thank you for that answer!

Your bench looks so nice! It feels like I just want to sit there right now and start doing electronic testing. :)

btw. lenght of your test leads (kinda) look a bit short IMO. Maybe if they were.... 60-70cm they would be better for me. I guess I would have to go with 1m as you suggested, until I get used to shorter cables (test leads).

Thanks! For more (and more serious) inspiration on bench and lab layouts, here is an entire thread with more photos than you ever wanted to look at: ;)

Agree, sometimes the 0.5 m leads are a bit limiting. I do have longer ones (in that large and messy cupboard...) and use them sometimes. As mentioned earlier, if you start with a pair of 1 meter leads, I think you can't go wrong.
