Right ... Just been nudged to set this up by Paul.M and sounds a good idea following recent threads I've done in the Arms..

Rules....No Offensive material... edit if required before posting as this is the public arena.
Anything to do with the trade or in and around it ...H&S pic's welcome.



I've posted this a few times and this is at a mates house following a kitchen refirb several yrs ago. mg_smile:

Spotted in a well known wholesalers up north that's being refurbished so they have a temporary counter...

ruddy hell thats bad..

Did an EICR of 4 static caravans, this was the CU in one of them
Note the 63A MCB for the lights! and the 32A for the radial 1 gang socket (Extra Point).
Previous inspection done by NICEIC

That figures, you mean a NICEIC registered Electrician I presume?

It astounds me what I see sometimes I know we're here to earn a living and make money but we are supposed to be a professional trade.

I think most Trades are supposed to be professional Ant, the main problem is amateurs doing work that they have no right to do, or "qualified" people attempting to do stuff they have no idea of what they are up to.

I do indeed or at least it was a NICEIC inspection label

Lights is clearly wrong should be Max 16a, but what's wrong with the socket? 32a would be fine even in 1.5mm cable for a single socket within reasonable distance etc wouldn't it?

Hi - 'fraid not .
You won't get 32A rating from 1.5 or 2.5 conductors. Likely it should've been a 16A mcb. You are right that perhaps a single socket should not be loaded that highly, but it could be loaded higher than the cable and less than the mcb => fire risk. What they're doing with the power circuit in the bathroom is intriguing ...

In theory see where your coming from but we all know it's wrong.

you guys might have to bring it down to my level as I'm not a pro

My thinking is single socket max load would be 13A (assuming no "special" fuse in the plug), 1.5mm cable depending on installation method could be up to 20A. How could the cable be overloaded?

With the lights taking 63A they will need to uprate their RCD, it could be overloaded!!

The cpc csa of 1mm² may not be large enough to handle the fault current; the omission of overload protection is not one that should be applied lightly and is generally not really necessary in domestic situations and certainly not in this case.
16A limitation for lighting is only with BC or ES lampholders, which might well be in place here.

Again correct, but only with clipped direct. Installed in a mobile home 16A likely for 1.5mm. Anyway, from a design perspective, Reg 433.1.1 (ii) says protective device current setting (In) must be < = the conductor current carrying capacity (Iz). This ensures the device operates before the conductors overheat and damage the cable.

thanks Richard and Wilko

agree, I have been caught before by that one, if the Zs is high enough would be fine, but I specifically mentioned overload.

It happens every time you install an unfused spur I thought? Also commonly used for showers where the shower rating is lower than the cable rating, but there is no MCB available between the two.
I agree that on a new circuit you wouldn't do it, but when doing an EICR you have to look at what's already there and know if and why it doesn't comply, rather than just say it's not what you'd do. That's the side I struggle with and would like to understand.

Anyway, from a design perspective, Reg 433.1.1 (ii) says protective device current setting (In) must be < = the conductor current carrying capacity (Iz).

true but only where the OPD is necessary: 433.3.1 (ii) allows the overload protective device to be omitted completely in this case (load not liekly to carry overcurrent)

That was for a wall mounted fan heater which was correctly positioned regarding zones.
