An interesting concept that I'd not come across before John. I can see the theory but I'm not convinced I need it here. I think I'd need a bit more than an RSComponents 1/4 watt carbon - what do you reckon :lol: |
| John Rudd:
Hmmm lemme see, 1/4 watt carbon? Err nope, I dont think it would cut it.... The NER's we had with our gensets were housed in metal enclosures that were quite large....in excess of a cubic metre, easy..and a seperate relay protection panel... |
| awemawson:
From what I read, they are more applicable to REALLY large gen sets, not this tiddler of 110 kva |
| Pete.:
Our towables are all earth-neutral bonded AFAIK. Not sure on the hired-in jobs but out 45/60/70/100's were all like that. |

Here regualtion requires one point earth/neutral. Simply put: 1: For tools etc. single consumer "machines" athe generator end is feeder and safety ground (etc.) there. 2: When generator is connected to residental emergency power or work distribution panel - that is point where all neutrals and grounds are connected. 3: No mix and match: Strictly forbitten to earth separately at generator end and distribution panel and connect with earth/neutral cable(s). Apparently too high risk for circulating currents and fault modes will multiply. I am sure that there are many industry/trade/country spesific deviations that work remarkably well on those special circumstances. I have seen generators that have all wires brought from pable outlets into a box that has terminals to wire generator sagety ground to which ever combination to N/G outlet terminals - or disconnect them with links and this would give easy option for groung from either end. |
