Scenario 1
200A Supply into a busbar chamber, this supplies numerous distribution boards but someone has wired a 6mm cable into the busbar which feeds a 20A fused isolator, so potentially you could only draw 20A through the 6mm...

Many cable drops in internal studwork which will be insulated with glass batts (as per building regs for interior sound isolation). I am radiussing top support in wall top as per Appx D OSG, hence no other support technically needed for the vertical cable drops. I'd very much like to not clip...
