Discuss Flex for fixed wiring in the UK Electrical Forum area at ElectriciansForums.net
I do still call them IT. Times have changed DPG, for the bloody worse.!!I give up? Was that in a Christmas cracker or something?
Have a check on Google - you will see they were orignally (and still are by many) referred to as plug tops.
I remember.Do you remember the old MK fused spurs with flex outlets Daz ? They had the same type of screws as the plug tops on the load terminals.
It is not wrong, although I agree it isn't used much these days. I suggest you read some old books on electrical engineering, installation, etc. It is the full name for a plug. It never meant the top cover of a plug!
A quick Google check shows that at least Farnell, Tool Station and Amazon still refer to them as plug top, amongst others.
If it is a plugtop what is it on top of?
It is on top of a plug, many years ago sockets were called plugs, and what we now call plugs were called plug tops.
I think the terminology changed when bs1363 came along
I know that. That is why I wrote above:
"It WAS the full name for a plug because a socket WAS called a plug. We have moved on now and those old terms are no longer appropriate or correct."
People need to move into the 21st century.

Went on a bit this post but in my opinion if someone has mounted a back box and socket front to a wall wired it in flex but has fitted a PLUG to the end of it this is just an extension lead as it can be disconnected by removing the plug rendering the socket dead.
The second one sounds like the OP may of meant wired into the back of a socket in which case this would be deemed dangerous as it is wired in 1.5mm flex acting as a spur but will have no means of isolation or protection in the event of a fault as it has been hardwired into the back of a socket which is part of the fixed wiring of the house and will more than likely be connected to a 32 amp cb rendering the 1.5mm flex unsuitable and the weakest link.
If that is the case it would be automatically disconnected and the owner would be told why.
Does it matter, old hands understand.?I know that. That is why I wrote above:

Your post may be disputed by some members regarding flex used for fixed wiring Chris.Hello All,
Hopefully this question will be sufficiently related to the OP`s thread to be allowable:
With regard to Flex cable being used for `Fixed Wiring` - I think that I know that it is NOT allowed by the Electrical Regulations - certainly not to be run under floors of in stud walls etc.
However for Years quite a few Heating systems that I have installed where the Boiler had a Pump over-run with the Pump having to be wired to the Boiler and also 4 core cable required `to the Boiler` has had the Boiler supply cable and the Pump cable run [usually from the Cylinder cupboard] in Heat Resistant Flex [`re. connecting to the Boiler`] - by the Electricians that have carried out the Heating Controls wiring.
The Flex would definitely have been run both under floors and within stud walls to get from the Cylinder cupboards to the Boilers.
I have queried this on various occasions - asking whether the Boiler 4 core [inc. Earth] and the Pump 3 core [inc. Earth] should be run from the Cylinder cupboard / Wiring Centre in Flat cable to adjacent the Boiler and then `transition` from Socket boxes to Heat Resistant Flex - exiting through flex entry / exit plates to connect to the Boiler.
I have usually been on friendly terms with the Electricians so there has been no perceived animosity / bad feelings about me asking that.
However this was almost universally rejected by the various Electricians that wired my Heating systems - and those Electricians would have issued Certificates for the whole Property`s Electrical installation including the Heating Controls.
What I described about flat cable being used from the Cylinder cupboard to adjacent the Boiler and then transitioning to Heat Resistant Flex was done by at least one of the Electricians over the Years and He stated that I was correct to expect that the Heating Controls wiring was installed in that way.
Sorry for the long preamble - my question is:
If as I suspect what I described about the Fixed wiring is the correct way / the only correct way [?] why would at least 6 or 7 Electricians use Flex without any hesitation [and after being asked about it by me] for the `fixed wiring` section of the Heating System Controls - knowing that they had to Certify the whole Electrical Installation - usually a complete Re-wire & Consumer Unit and the Heating controls - ?

as far as I'm concerned boiler wiring is "control" wiring and therefore use of 5 core "flex" is perfectly acceptable......

Interesting timing ...........over in the plumbers forum I have just said that as far as I'm concerned boiler wiring is "control" wiring and therefore use of 5 core "flex" is perfectly acceptable......
off to my bunker now with tin hat on!
The regulations do indeed allow flex to be used as fixed wiring as long as it’s the heavy duty type unless the risk of damage during installation is low etc etc, types of flexes are given in bs en 59565-1
For more detail see regulation 521.9.1 page 126 of bs7671.
