3 phase polyphase meter,, landis an gear

[fancypantsyeah]

i am sepperating a small unit from the main building next door. the owner wants the said unit on own supply and on own meter to resell the electricity , i have seperated the circuits involed , a 10amp lighting cct, a 32 amp ring final and a 3 phase 32 amp isolator . i have placed the ccts mentioned onto a 3 phase tpn+ e DB..i have run a25mm2 swa able TO SUPPLY TIS NEW db FROM the main buildings DB which is a 3 phase 3 wire system to the meter enclosure... MY PROBLEM IS THE METER CAN BE WIRED INTO A 3PHASE 3 WIRE SYTEM BY USING THE L3 AND CONNCTEING IT TO THE NEAUTRAL POINT IN THE METER WHICH IS DIRECT WIRED... AFTER LEAING THE METER DOES THE 3RD PHASE WHICH WOULD BE WIRED INTO THE NEUTRAL POINT OF THE METER THEN GET CONNECTED INTO THE MAIN ISOLATOR AS I NEED A 3 PHASE SUPPLY FOR THE 3 PHASE ISOLATOR ...HELP PLEASE AS YOU CAN SEE THIS IS THE FIRST TIME I HAVE WIRED A POLY PHASE METER INTPO A 3 PHASE 3WIRE SYSTEM...:dizzy2:

Not unless you want to blow the meter up.

I think you need to be a little more concise here.

Your lighting and RFC is single phase, do you actually need 3 phases into this split unit?

If no then just fit a wyefield distribution board at origin of the installation with your 3 phases, after the original 3 phase meter at the head, and then run a single phase supply to a single phase meter.

If you do need 3 phases to the unit, then run your L1 L2 L3 and Neutral to a 3 phase meter a connect L1 in L1 L2 in L2 etc etc
