House vs Domestic battery labelling

Thanks for most of your replies :)
To clarify, I wanted to use terminology that everyone in the boatyard would understand when moving my boat while I am away. Including fairly junior staff.
I think I'll go for Engine and Domestic. I know Domestic isn't a complete description, but it seems to be widely recognised.
...in which case 'Engine Start' and 'Everything else' ?
 
'Service'? That's what I use.
I go for "service" too. "Engine" is acceptable because it's unambiguous. Any thing else on a boat that needs electricity to function is going to rely on a "service" of electricity. To call it "house" is, I feel, wrong because it's servicing a boat. Big difference :). Again "domestic" isn't truly descriptive of its purpose. Easy to overthink the question though.

except when either battery could be used to start the engine but only one is in use all the time.
The original question implies that the 2 banks are independent as he also refers to paralleling. However it is a non issue and doubt that any boatyard employee could ever be confused or cause any damage because he did not understand the label, or even if the switches are not labelled (Op's reason for trying to establish the "best" label!)
 
Actually it was very easy for me. The Engine uses 24v and everything else apart from the Windlass uses 12v. So the 24v is called 'Start Bank' and the rest 'Service Bank'. There is an 'Emergency' system (12v as well) which is for the small engine on quarter installation
 
Mine are "Engine" and "Service", because that's what they are. On my previous boat they were Port and Starboard, because they were identical banks. (Long story, believe me there was a reason).
I can't believe that anyone would be worrying about such a trivial matter. ?
