What do you mean by "changed for trip types mate"?
What HP is it Ethan?
I've only worked on small induction regulated motors, up to 50HP. Never did like them.
Couldn't have got closer to the centre if they'd measured it!!!Changing a CU as part of a house referb, stripped the old board out and fitted the new board with basic circuits for work to continue, and tested the remaining circuits ready to couple up. A quick check prior to the couple up showed line-CPC fault on upstairs lighting circuit. Great! Newly plastered ceilings, walls etc boarded loft, tiled bathroom, laminate floors.
Ho hum, out with the Fluke and round I go trying to narrow it down a bit using the 'getting warmer, getting warmer, colder now' resistance test. Pinned it to the landing light being nearest (thankfully not in the walls) and went into the loft. Second board I lifted and there it was. Could have been worse I suppose :-/
Imagine the scene,Friday afternoon about 3 oclock,office gets a call,a 2KW heater gone down in the securitys site office,(cant have the security guards getting cold,they wont be able to fall asleep)anyway i get the job to go and replace said heater,site was around an hours drive from where i was,i eventually get there report to site manager,then have to show my cscs and get inducted on site,all the usual rubbish.No risk assesment no method statement,site manager reluctantly lets me get to work,its around 5 oclock now and not even got my screwdriver out,site manager standing over me,i guess he wanted to go home,im rushing around like somebody possessed,isolate heater circuit and disconnect heater from SFU fit new heater to wall wire it up energise circuit test heater nothing aaaarrrrhhhh.Lots of colourful language by this stage,site managers pacing up and down,i ask him any chance of a brew. Well didnt get brew tested SFU,its not swiching no probs run to van get new SFU safely isolate again,but now have to dissconnect circuit cables,CPC and N touch taking out whole site,ask site agent for keys to CU,their on the way to liverpool,site sparks got them in his pocket.When a very angry site spark returned i set main switch and everything was fine.I left site at 19.30.The moral behind this story is rushing gets you nowhere fast.Istill didnt get a brew,but the guards were nice and warm.
Not really the right place. If you mean for PAT testing then the recommendation is up to 700W 3A above 700W 13A; but follow the manufacturers instructions and computers/ vacuum cleaners often have a 5A fuse.not sure if on right place here but can anyone tell me the right fuse against the right wattage please
i worked /did my apprentiship for meggitt marsh, we used to install ringmains in steel conduit with no cpc
the earthing was reliant on the socket fixing screws only
if the earthing was crap we just went around tightening the 20mm bushes in the ko boxes!
As long as there's a fixed lug you don't have to Rich. I was taught to take the cables to the terminal on the socket then a lead to the box and still do it to this day, for the amount of time it takes I deem it worthwhile but it's not a necessity.Why did you not just tag from the back box to the socket faceplate??
You would still need to tag it despite it being 'effectively' earthed through the screws.....
12 volts?- still ,i can,t understand why the installer did that--
probably a boy left alone, non supervised, or a clueless idiot
When I am wiring a socket on a ring final I WILL always sleeve the cpcs separately, I will connect the two from the cables (ring) into the terminal on the metal box. Then I will always have one cpc from that terminal to the earth terminal on the socket and when one wire is being terminated, I always double the end over.
