parallel and series lighting circuits

[fulham sparks]

i'm still in training but i still cant get my head around what these look like in twin and earth? can someone give me a description or pic of them please.. i do feel like a right knob for not fully understanding this.. cheers

Not quite sure what you're asking her. Maybe you mean the difference between daisy-chaining (looping from one fitting to the next) and spider web (supply to a common point , then branching out in all directions)?

 

[fulham sparks]

the looping is series right? i kinda get that... i'm not too sure what you mean about the spider web?

lighting circuits are not wired in series. they are always parallel.

unless specifically designed to run in series with 110v lamps etc. which would be unlikely

Is this an example of spider web wiring?

Took half of it out and found what looked like two feeds to two circuits. Conduit drops to a 2g switch on other side of wall. Then switch wire and neutrals to a load of fluorescent lights.

I was only stripping it out so not allowed to spend a lot of time working it out. Looked like one circuit per connector block strip.

Yup - that is an example of spider-web. Old type way of providing either multiple luminaires from one or two locations; or multiple single pole switch & luminaire feeds from one central supply point. In some cases, ALL the switches & ALL the luminaires comeback to the middle of the web, and are interconnected there - which can give some strange results (especially if brn/blu (formerly red/blk) is used for switch drops, and hasn`t been marked up )
