Canalis calcs

[Aaronj46]

Looking at a warehouse contract which requires 190M runs of canalis with 31 x 200w lights.

Volt drop is 0.72V per Amp per 100M for 25A 3phase Canalis and 0.3V per Amp per 100M for 40A 3phase canalis.

Am I right in thinking the 40A would be fine? Consultants have said that they want the runs to be split in half due to volt drop, done my own calcs and 40A is fine.

Thoughts/ calcs anyone? Beginning to think I've gone mad?

Thoughts?

Yes, never argue with a consultant or waste any time trying to convince them that there may be a different or better way to do something, just do what they spec and if wrong it's their fault.

Fully agree, just wondered incase my calcs were wrong for 40A being acceptable
