loop in at the switch

[Spark123]

Not too messy in RL, just a little bit messy to draw the pic and it be clear.
If you can follow what is going on here:

i can follow it i have had to follow many so called sparks who used this method got them self lost on the 2 way switches could not fit dimmers 2 way 2gang switches all cpcs crammed in to con block ect ect if you where meant to loop in at the switch why cant you get a 2 way switch with a loop and neutral terminal to me its just a diy method but time served and 30 years in maybe its just me

one last question if you went on site ie large project and started to use this method on monday site agent has a look do you think you would be there tuesday

 

[Spark123]

Shouldn't be a problem if you have given yourself enough room i.e. a 1" box, the big advantage of using this method is you do not have a bunch of wires above the light fitting, OK if it is a loop in ceiling rose but since these are no longer the fashion then it can become a bit messy!
If a spark can't follow a 2 way lighting circuit then there's something sadly wrong, however it is understandable that a DIYer can get lost.
How many 1mm CPCs can you cram into a peice of terminal block? In the pic there were 3 in one side and 2 in the other, not a big issue imho.

Am using a loop in at switch method for an outside light in an extension I am doing at the moment.
Can you give any constructive reasons why you believe it is wrong to use this method?

 

[jockspark]

outside light dp switch no problem now large project do you think you would be there tuesday

 

[Spark123]

Why not? What is wrong with it? Does it comply with BS7671?
What other suggestions do you have?

 

[jockspark]

we will have to agree to disagree every time i have seen this method used
its been don e messy and by a diyr seen it once on a large project the guy was sent packing there is no reg i can find to stop this practice but if its so good why no publications to teach it why no switches designed to use it so i think we will leave it there its one of my pet hates thanks for in put enjoyed my rant

 

[Spark123]

I don't think a small piece of terminal block in the back of a light switch constitutes a mess, I'd rather see it there than stuck above a ceiling where you can't get at it or above a fancy light fitting crammed in.
I don't see why a light switch manufacturer needs to take this into consideration, along the same lines as why doesn't a plastic light switch have an earth terminal? We just fit terminal block to the CPC as required when using DL boxes.

Here here Spark, I'm with you 100%.

There's people out there who insist that you should supp bond pipes in a kitchen "Because they've always done it that way"

I don't care to remember quite how many sites I have wired using this method.

It is my method of choice these days, due to struggling with oh so many stupid fancy fittings, where there really is not enough room for loop in connections.

OOI jockspark, what sort of work do you normally do, and how long have you been in the trade?

(I'm not being funny, just trying to understand why you don't like this method)

 

[jockspark]

as i said above 30 years domestic and industrial from house bashing to large industrial panel wiring most aspects of the trade over the years thats why to me this method seems diy i will try to explain one more time every time i have come across this method it is to fix the **** up where when they got to the 2 way switching and had do deal with loop in loop out and 2 way they pack up and **** off i have no problem when you do one or two switches
as i said outside light dp switch or one room but a time served spark would not set a whole job out in this manner it smacks of diy or 5 day wonder
now how long you been in the trade

 

[Spark123]

Me, 14 years coming up. 99% of what I do is industrial, including large panels!
If someone cannot figure out a 2 way loop in lighting circuit then they are not an electrician.
Why do you think that this method smacks of DIY of 5 day wonder, what is actually wrong with this method?

 

[RF Lighting]

Ten years in the trade, served a four year apprenticeship, and do mainly specialist commercial work

I work with plenty of sparks who have longer in the trade and are far more experienced than I am, and they are all quite happy to use this method, as it seems the majority of electricians who post here are.

It is not that different from cloth covered VIR singles in steel conduit from the ~1940s
That had the live looped in and out at each switch.

I tend to find the DIY way of doing lighting circuits would be junction box method.
