Question Were is the Best place to buy small amounts of electrical wire insulation?

[reaper89971]

I can't seem to find small amounts of wire insulation. The few places in the past were i would go have closed down.

I don't want shrink wrap, Looking for a regular rubber insulation.

I thought about just cutting up some rubber bicycle tubes but not sure if there made of rubber anymore.

You should look into heat shrink but I'd replace the PSU if the insulation on the wires are disintegrating.

You don't say what type of wire you're trying to insulate, whether or not it's operating below the SELV limit or on AC mains, single core, multi strand, coax, etc.

Check out PTFE sleeving, available in a number of internal diameters. Small diamters are best used on solid conductors, not multi-strand wire which might be more difficult to fit.

You can buy clear (transparent) or coloured sleeving. PTFE is good for temperatures up to 250C (better than PVC).

Why, specifically, rubber? Shrink wrap is just fine unless you're talking many thousands of volts and high current.

I would like to insulate 4, 120v 16 gauge wires and 8, 16 gauge, 24v 18.8 amp wires

The 8 24v 18.8amp wires are about 60cm long each 16 gauge wire. Witch is double the size of the 30cm FAT Playstation 2, I wanted some length to work with.

I wired up a Mean Well SE-450-24

It has the screw down wire terminals real easy no solder.

Im using the Mean Well SE-450-24 to power my HDPLEX HIFI DC-ATX 500 watt

I have 2 of these plugs for the 24v 18.8 amp

All of which are readily available by the roll, already properly insulated, and in the color/s of your choice. There's no need whatsoever to be reinventing the wheel as you seem so determined to do.

I'd be cautious about "bunching" 120V wires (above SELV limit) with 24V wires (below SELV limit) in the same cableform. It's not good engineering practice.

I would certainly NOT route 120V wires and 24V wires through the same connector. It's just asking for trouble. No way would you get UL or CE certification with such a configuration. Keep high voltages and low voltages separate, or double insulated.

I don't want shrink wrap,

If you're dead set against using heatshrink, consider flexible braided Megamide:

Alternatively, there's spiral binding:

Im not putting the 120v with the 24v together i was going to have them be separate

Hey would you happen to know of a good mini fire extinguisher made for pc electronics. That isn't a piece of junk. That is trustworthy.

I did my own wiring and had someone else wire my atx power supply and we are only human and make mistakes. So i would like to be prepared. I have a regular fire extinguisher but its not made for electronics.
