1999 20l 16v stage 1 35nmstage 2 70nm
stage3 +160 deg
bolts sequence 8 4 1 5 9
7 3 2 6 10
hope this helps daryl:D this comes out wrong for sequence should be put 7 under 8 3 under 4 2 under 1 6 under 5 10 under 9 you start tightening from middle
Thats what i thought advise not correct just to cover myself cant see that my work is making it any worse,at the end of the day were are not here to just bang in new circuits as our builder friends would like but we follow correct guidelines thanks daryl.
Well was working on original question hyporthetical 100A
16mm cable 70 deg pvc clipped direct volt drop 2.8mv per mtr
2.8x100x60
-----------
1000 = 16.8v so 100-16.8=83.2 so 83A 100A circuit breaker wont opperate in time hope i am right on this like the original question...
Can someone correct me if i am wrong just calculated volt drop as 16.8v so current carrying capacity is about 83A so 100A mcb would be too much need to downsize
Just one more question on this because i am adding to circuits does the main 30mma rcd cover this as the 17thed says less than 50mm deep,i thought this would be ok and in the remarks columb to say that cicuits not segragated only one rcd consumer unit is old wilex with retrofit mcb's with rcd...
