ok but if the voltage on the conductor is 240v isn't the driver 0v so that would be a PD? probably seems silly to u but im trying to understand it totally :D
and by saying surge i was meaning when a short circuit occurs and trips the mcb say,the current has increased to do this yeah?this is...
another simple question?
here goes.....say if i touched a phase with a screwdriver its going to blow right even tho the driver is insulated,isn't it in theory just like adding more cable to the circuit?well at least if it was a copper driver :D
sorry if this seems stupid again but been...
yeah seems to have gotten a bit heated over what was such a 'simple' question,doesn't seem that way now. and i dont think it is too basic,maybe the way i worded it made it look like i didnt know how a circuit works,i do but didnt totally understand why there was 0v at neutral end thats...
clearly not a fault of mine :D
and as the jobs i work on are mainly schools and general large commercial projects i dont get experience of all different systems. the lights we use are mainly prewired 3 or 4 core flexes which just plug straight into back of the light and an lcm,this is the...
wow thanks for all the information,much appreciated and helped clear it up somewhat :D
so when the current has been used by the load and returns through the neutral wire,finally being connected to earth back at substation,it is for want of a better word dissipated into the ground?it still has...
i do understand how a circuit works,but this doesn't explain what i was meaning,my main query is how neutral can be termed 0v but still has say 230v running through it?
just a general question here,i am an adult trainee in my 2nd year and after asking a few trademen in my workplace this question i couldn't get an answer i understood,most of the answers were 'it just works like that so accept it' :D
there seems to be a lot of knowledgable people on here so...
yes under supervision :D was just curious of how it was done as hadn't done lighting circuits in 3 core and and earth before,only singles.
ok now though been shown how to do it,i was mainly looking to find out where wires would go,i.e going straight into switch with 3 core but putting neutral...
they are large flourescent ones,about 1500mm in length,its for a project im doing at work,meant to say 2 of them in one room and another in the other room are emergency to be non-maintained,would i have to use 4 core for this or wcould i just link from the live?
ok thanks,so i would go straight into 1st light,loop in all the way to last light(connecting lights in both rooms together?)then run from 1 light in each room to corresponding switch in normal 1 way wiring?
hi all new to the forum and have a little question :D
im wiring 2 seperate rooms of lights using twin and earth,i have 2 seperate switches,1 switching 2 lights and the other switching 4.id like to switch them independently of each other,so how to i do this?
do i run my live into 1st switch...
