exporting pme

[davelerave]

if (for arguments sake)you're exporting PME with a swa submain-not converting to TT


can the 'main bond' be used as 'cpc' or should they be separate

should the main bond be at least minimum csa required and kept to less than 0.05ohms


thanks

Where a circuit protective conductor also acts as a bonding conductor, the requirements for both functions will have to be met.

Also remember that the sizing of the bonding conductor on PME systems is based on the SUPPLY neutral CSA, not the distribution circuit neutral.

yes i'm aware of the basic sizing requirement -i'm referring to longer runs

what does first line of your post mean exactly?

It just means that as well as meeting the requirements of regulation 543.1.1 for a circuit protective conductor, it must also meet the requirements of regulation --- (can't remember whatever replaced 547.02.01)

For the amount of times this question is asked im wondering if we claim back VAT for it!

one conductor will do both but it must be minimum size required for either(usually the main bond)

is that what you're saying ?

max resistance of main bond is 0.05 ohms?

That's about the size of it!
