Hi

Rigol states 'must use wire rated for 9A or greater to prevent damage or a possible fire hazard'.  That's 12 AWG.

https://rigol.desk.com/customer/en/portal/articles/2285140-how-do-i-connect-the-dp832-to-achieve--30v-on-channel-1-and-channel-2-

That seems to fit in with the 3A per channel maximum but if the project is only a lower current one, wouldn't it be ok to use, say, 18AWG wire ?

Thanks

They are being over-cautious.  However if you ignore their recommendation, use thin wire, short it at max current and as a result mar the front panel or melt a notch in a binding post insulator, you are S.O.L.

I've located some ring mains cable to I'll use some of that.

Thanks.

You don't need to handle more current than the total CC you set.  For example 50mA each on the rails and 150mA on the digital section will need at most 250mA.  And you should set CC limits; this is what will save your projects when you do something stupid.

Just your typical lab 4mm banana jack equipped patch cables are fine, like basic Pomona ones.  Pomonas specifically are rated to 20A.
Ian.M:
Personally, I'd get some stackable 4mm plugs and make up some short jumpers - 6" between plugs would be a convenient length.   Alternatively, if you rarely use the binding posts to clamp wires, make up custom jumpers for each configuration with crimped fork terminals, with multiple ends depending on the number of terminals you need to tie.
