Discuss Electrical Pool cafe project in the UK Electrical Forum area at ElectriciansForums.net

Welcome to the forum mate.
Can you be more specific in what you need help with.
 
Is this a college assignment mate?
 

It is a bit hard to know what the OP is talking about.
Not sure what "4 hotel rooms" has to do with 'Electrical Pool Cafe Project'
Maybe he/she will come back with more info.....
 
Or it could be another member posing anything so they can start a spam bot in a bit... Who knows...
 
C&G 2365 & 5357 design unit.

See attached pdf file of the drawings layout.
