I find this a little unhelpful that some push fit are designed to accept stranded and others are not.One standard push fit connector would be better.
Undoing some pushfit connectors that have stranded cables renders the connector unusable (according to Wago,s instructions).Not helpful.Why a...
Yes.Perfectly fine from an electrical point of view.But your regs might require it to be a little bigger (4mm?) due to mechanical protection considerations."pc1966" is better placed than me to a swer that.
Correct.I always bond the metalwork to the CPC .I understood from the OP that he wondered about running a separate bonding cable to the metallic structure.
I would say yes,technically, as it can "introduce a potential ", if it's sitting directly on earth.
But it differs from the conventional extraneous part in that it is introducing a potential to itself rather than other unrelated metalwork.It simultaneousely serves the purpose of been both...
Not necessarily.If there is no extraneous metalwork entering the container then in principle there is nothing to bond.
It's no different from the metal sheds commonly erected nowadays.If there are no metalic services entering the shed (such as a water pipe) then there is nothing to bond.
Thats a very interesting point .It would explain why these very same fans are installed all over the continent and are protected ,not by a 3 or 5 amp fuse ,but by the 16 amp circuit mcb.
As far as I am aware manufacturer,s only seem to get away with this in Ireland and the UK only.In other countries manufacturers are expected to take care of this issue themselves by fusing the appliance internally
Why would the distance to the PME,s electrode matter?.The general mass of earth is a conductor of negligable resistance.The usual considerations taken in to account are the resistances of each individual electrode (installation and PME,s) to the immediate ground they are sunk in to.Whether the...
With readings like that you most likely have an appliance still plugged in.Or there is a fixed appliance still in circuit . Its very difficult nowadays when carrying out EICR,s to have 100% of the circuits"clean".Invariably our low IR readings gradually improve as we isolate the "offending"...
Am curious about this comment.Just wondered if it was down to the unavailability of the correct busbar for double pole Hagar rcbo,s that required you to wire them individually.?
correct.It is,nt.
I think the issue may lie with the "Cat 5" label.That is as far away from tap water as you can get.
Bearing in mind that the resistivity of water drops considerably when pollutants are introduced to it ,that would be my first area for investigation.
Is it actually allowed to...
Confusing sums it up well.I looked up several sites and quite frankly you could make an arguement for either case.But the advantage of discussing "tap water" is that we all have easy access to it.I myself have taken my own IR tester to it on several occasions over the years and my readings were...
Are you sure those figures are "per meter"?.Some sites give similar resitivity readings (researchgate.net) "per centimeter".JW,s readings would naturally be a hundred times higher and add significantly to the overall resistance
His readings are from the "actual water".The copper ends that the...
No.Its a receiver.Its also the property of the DNO
Am equally uncertain but its also a part of the DNO,s property
Good decision.
On closer inspection I can see that the device to the right hand side of the fuseboard is actually a main switchfuse and not an rcd.
It now appears increasing...
