Yes male pins at the 13amp wall socket end.
It's  a good thing you are asking these questions, you would not be the first to make a cable that falls into the 'widow maker' category, please make sure you get an electrician or someone suitably qualified to check your cables over before you use them.
Simple rule here is you should not be able to touch a live contact on your mains cable.

For a 25M run I would go with 6mm2 of HO7RN-F cable with 32 amp connectors and tails as described by 4D also using 1.5mm HO7RN-F cable.
Using 2.5mm cable on a long run may put you on the edge of what is an acceptable earth loop impedance.

And rather then a 4/6way socket thingie why not spend a penny or two more and build a small distro box? A cube with a double 13A on each side and maybe an RCD thrown in. Should be "cheap" enough. That's what I would do anyway



I've got 5 metres of actually good quality 1.5mm 3 core cable so yeah I could easily make a 6-12 inch cable with a 13A plug to plug into the wall with a 16A Ceeform on the other end and then near the 6 gang socket have a 6-12 inch 1.5mm cable connected to it as well. You mean make one out of wood and then attack two double 13A sockets to it?

I think that might be a case of running before learning to walk.

If ever you intend doing any outside gigs then use Rubber H07 RNF 2.5mm cable as this is the correct cable for the job..... Do it now and you will only have to buy once!

There is a guy on eBay who is doing a good deal on ceeform H07 cables. He is selling 25mtr ceeform H07-RNF for about £40 inc. P&P.

 https://www.ebay.co.uk/itm/16A-H07-2-5mm2-Rubber-extension-power-cable-stage-event-catering-16-AMP-NEW/142934790605?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20131017132637%26meid%3D258680003c6641b88a5e78be5e0bcece%26pid%3D100033%26rk%3D7%26rkt%3D8%26sd%3D153280070119%26itm%3D142934790605&_trksid=p2045573.c100033.m2042

 

I have no connection with this seller so cannot vouch for him/her but spotted the listing earlier today.

You're right. 6way it is.

And most of my adaptor cables are super short runs and I haven't come across any problems yet... and some of them have a solid 10yrs on them

Yes. But as I said, that's what I would do.

The ONLY reason I suggested a little distro cube was to stop the cluttering of plugs and Wall-wart adapters from getting clustered and not quite being able to use all sockets as some big ads power supply lead is leaning over another socket making it impossible to use. Just to space out the sockets really... no real technical reason.

Reality check. For the 1 or 2 amp draw this will be you could use just about any electrical cord that is long enough.

Nope,
If your going to bother making up a main feed cable you may as well make one that will have negligible voltage drop for the gear your intending to use it with, minimise voltage drop and earth loop impedance, using a thick gauge cable will ensure that your not tipping the loop impedance over the edge so that your earth actually works as intended. HO7rn-f is a requirement for temporary outdoor and larger indoor installations.
A 13amp plug will allow approx 26 amps through it long term over 3 times that short term, it would nice to be able to take advantage of some that when your amp psu wants to recharge after a large transient signal.

In that case just don't bother with the long cable and take a split off the feed to the smallest amplifier, really no need to use the other sockets at all.

I agree with above, that if you're going to make up these cables, make them up for all situations, not just this particular case.

So use appropriate sized conductors for the length of cable at the load it 'could' carry

In that regard, he should also make sure the 6 gang plug board is fused if it's going to be fed by a 16A plug rather than a 13A fused plug top.
This way if he ever uses the long 16A cable plugged directly into a 16A outlet, the plug board has protection (which in his use case will be provided by the fused 13A plug into the wall)

WallSocket:13A Plug<-1.5mm->16A Socket:16A Plug<---2.5mm--->16A Socket:16A Plug<-1.5mm->6 gang fused plug board

Or

WallSocket:13A Plug<-1.5mm->16A Socket:16A Plug<---2.5mm--->16A Socket:16A Plug<-1.5mm->1 gang 13A socket:13A fused plug<-1.5mm->6 gang unfused plug board

That's easy to understand thanks I really apreciate all the help from you guys.
