Is there anything in the regs. about the size/wording/colour of the warning sign to alert people that there are two cutouts on a mains circuit? I have a big CU and then a split tails shower (63A) unit quite close to each other in the pantry. I suppose any sparkie would immediately see these, but I'd better get it right!
Wording/size of warning notice?

Sorry for being a bit vague. Basically, we're having people staying here while we're away and we have the two sets of tails from one supply, so I want to make it obvious that the main switch on the CU won't isolate the shower. For this, you need to flip the MCB on the separate 63A unit. I know that the regs. insist that this be advertised near to the incoming supply- just wondering if there's a correct way to do this, apart from putting a great big sign in the pantry. Yes, of course I'll tell my visitors, but it's not really the type of thing you remember in an emergency.
Our local wholesalers sell
Red "MAIN SWITCH" labels
one on each consumer unit by the main switches would be a start.
most CU's are supplied with paper stick on ones already
No label in the regs Afaik, unless you are supplied by mains and a generator

Yes, I would take it one stage back and be more concerned about the fact you have no 'one point of isolation' for the installation.
537.1.3 and 537.1.4 would apply, but not sure where the one single point comes from.
Most older premises with henley blocks etc, often have more than one main switch

I'm not 100% sure where the single point of isolation comes from too - I know a lot of installations where this could not be complied with.
As long as there are clear instructions that there are more than one point of isolation then I don't see the problem.
