Welcome to ElectriciansForums.net - The American Electrical Advice Forum

Hi guys,

Just wanted to clear up how to wire a switch feed light circuit.

Ov we have our power in and power out at the light switch.

We then have the live to common and also another live at common for our power out.

We have the neutral in a chop block for power in, power out and To the lamp 3 in total

We then have a live from the lamp to L1

We have the earth in and out in the earth terminal inside the switch

Is that the correct way to wire a switch feed light circuit?

If I understand you correnty. You want to have the loop in at the switch.
So you have brought the live and neutral feed to the switch and then you have a live a neutral from the switch going to your light?

If that is correct then the way you have described the wiring would appear to be correct but I do not know why you need 3 CHOC blocks.

The live feed in goes direct onto COM on the switch.
The earths will go on the earth terminal on the back box (or on the earth terminal on the switch if its a metal one.
The switched live out to the light will go on L1 on the switch.

That leaves you with the neutral in and out. Those two go together in a bit of CHOC block.

Simples!

And wouldn't we a neutral going the the lamp also combined at the chop block with the other two neutrals

why not use a double pole switch then no need for the choc in the switch

The Old 20a DP's have a bit of a 'heavy duty' switching action though don't they, something some old dears might not manage to easily!

Hager lightswitches have a spare Neutral terminal built into the switch, maybe other brands (likely are some others around) should start doing the same thing.

^^^^ Didn't even know hager made accessories, however, the spare neutral terminal seems an excellent idea

I'm still trying to understand you.

Do I now understand that you have
one cable = a live and nuetral in
one cable = live and neutral out to another light/switch
one cable = switched live and neutral going to the light itself?

If so then the live in and out go to com on the switch
the switched live goes to L1 on the switch

If so then, yes, you'll have all the neutrals together in a CHOC block (not a chop block please, a chop block is what the butcher beheads chickens on)

Blimey, this is hard work, Paul. I am rather worried about YOU.
Back in April you said you were doing your C&G, not worried about your <ELECSA> assesment and
I feel I am competent now
Mate, wiring up a light to a switch is about the most simple thing you could do as an electrician.
I would abandon all thoughts of going for assessment for a very long time.

I think the short answer here is: Yes.
