Got me thinking how likely it might be that they have also converted the neutral to tncs at supply. There wasn't much sign of this supplies went to a ryfield
Thanks chaps. The thing is these apartments were built maybe 80's and all the properties I've worked on in there are done the same way and none are glanded correctly. Don't seem like many sparks nowadays can chuck their hand to this (including me) and don't know what chances are of getting the...
The whole complex is done like this Dave there's about 200 properties. I'm not entirely sure what the proper name for it is but if you look at the photo the pipe comes in and has some sort of orange outer sheath then what looks like copper pipe is exposed and earth clamp is clamped to this. The...
Evening all
Had a job yesterday, which I'm back at next week. Job was to install new dual tarriff CU. As can see from photo earthing was supplied off a clamp from incoming metallic pipe which contained the supply cables. As this old CU is double packed out with a frame it had ample space to...
It's tns. Consumer unit is right next to front door. Ground floor property. Hard floors, stairs in way and even if could get access through stairs then in kitchen full of fixed appliances on wall would need to run circuit. To much hag for me I think I'll give it a miss. Thanks for replies all
Thanks Matt. I hear you that this maybe isn't great design, not decided fully yet on how will go about things. So to clarify then, every ring that is installed and isn't taking into account the potential loading on the legs does have a potential if heavy loads on short leg to actually overload...
Can you explain to me what the likely problems are other than not great design? If 2.5mm rated at 27 amps and supply a 25amp mcb from this how can the cable potentially be overloaded? If draw 25 from outhouse the mcb for outhouse kicks in and if draw 32 in total the one at CU kicks in
I get what your saying but going with 32amp MCB in enclosure just pretty much negates the need as have 32 back at board. I am also concerned as others have pointed out if load all on short leg could be overloading this leg of ring. Think I'm more inclined to go with 20/25 atleast then if they...
Hi mate
Thanks for that had a good read of it. At this stage I think I'm more inclined to go with a 20/25 amp MCB in an enclosure and take a 4mm to outside socket then down to outhouse
Thanks Little spark that's really helpful. Unfortunately yes solid floors and loads of obstacles to get past for new circuit. I'm considering the option 2 you mentioned. So could potentially use something similar to 2 way CU? Take both my 2.5 ring conductors into top of 25amp MCB. Then use 4mm...
Thanks Matt. Do you mind clarifying why? What would you do in situation like this where no option of new circuit and 13amp spur very likely to get overloaded?
Hi all back again needing more advice.
I've included some photos. Basically customer has asked me to supply and wire outhouse. Unfortunately as consumer unit is at front of house there's no real possibility of supplying on own circuit. The outhouse will have about 3 x double sockets and couple...
