Landlords override switch

[mag8485]

Ive been having a look at this wiring diagram and i understand the function of the overide switch but i am not sure about how the emergency key switch is wired in this diagram. Is the diagram wrong? surely the neutral should not be wired into the switch but the line at the light instead.

Could someone help?

To me that is wrong but then again i'm not sure what has been taught to you up to now, there may be a reason for them to take a neutral to the key switch? is there supposed to be a neon light next to it? are they planning on doing loop in at the switch for the emergency light?

I just googled on landlord switch wiring diagram and got this result. I think its a mistake but then again unless its gonna be looped to a emergency light

i dont get it at all, i could understand if the live and neutral came out from the board and through a dp keyswitch, but the way this is looking what purpose would the keyswitch serve?

 

[Sintra]

Can't understand that either.

I reckon they mean take the neutral to a DP keyswitch before it gets to the bulkhead (and the line to the keyswitch before it gets to the common). Just badly drawn.

Definitely not right. I did something very similar to this in a fica practice bay at the college once.

can you help me
in the fica when you operate the landlords switch the light has to come so when you operate the 2way intermidiate nothing should happen as the landlords switch is operated

can you wire your circuit as normal 2 way intermidiate. take a feed onto the landlords switch then just take another switch wire from your landlords to your light,

therefore you will have two switch wires at your light


ie

main board to 2 way feed strappers through your 2way int 2 way switch wire from other two way to light, feed from first two way onto landlords then from the sw of land lords to the light

Some landlords need to have an overide switch

 

[9regnac]

It has an over ride

The over ride is over riding the two way plus int as describe

Its the lihhting circuit in the fica

 

[nickblake]

if its an overide to keep the lights on then the live from the bulk head need to go to the key switch not the neutral other wise its Bang

I'm not sure about the emergency key switch because the way it is drawn it looks like it may be a protective device test switch!!!!!
