Switching

COULD ANYONE SEE A PROBLEM WITH SWITCHEN 50 X7 WATT LEDS AT ONCE http://www.websparky.co.uk/acatalog/WS-inceptor.pdf

i'd split them between 3 or 4 switches. not because of the load, which is only 350w, but consider inrush, and if on 1 switch, a fault anywhere will take the lot out.

Why? Have you?

 

[i=p/u]

No but i have 154 too install in a room was thinking 50 each switch and 4 as last man out switch around that

Retractive switches and a couple of latching relays if they're going to be on all day or above couple of circuits for a bit of discrimination so you don't lose the lot.

NO , looking at under 2 amps
i know that there could maybe be inrush of current regarding the drivers so mybe use a type c breaker

 

[i=p/u]

What size of glands would i need for 16mm 5c swa???? Better by 2 pks cause the first is bound to get thrown

 

[Guest55]

no way would i put 150 lights on 1 circuit on a commercial install regardless of how small the current draw is.
50 over 3 minimum.

I have fitted 20 7w aurora's on 1 circuit... never again...

on occasions it would trip the 10A MCB when initially turning them on.

the inrush on the LED's are high.

treat them like a 50w downlight..

 

[i=p/u]

Yeah il use 6a type c and thinking maybe 6 circuits rooughly 25 each ..

What about that gland ive only ever used 20w isit?

Have a look on SWA's website there is a table :winkiss:

good idea ;-)

might need a 10A mate

and why dont you read on the back of the SWA pack.. it will tell you what size gland you require..

probably a BW32 or larger

I would recommend a 6 gang Switch M8, not on one gang myelf, and have them on 3 circuits, 2 switches per circuit, I dooney like more than 8-10 lights on one switch myself and start feeling uneasy at more than 15 on a circuit, however in answering your question load wise no problem, but good practice suggests otherwise,JMO.

32 it is men... This is big job for me, cant afford to get it wrong...
