timer for lighting 3 x 150w halogen

[i=p/u]

as from one of my earlier posts, i have been asked to install these fittings if i was to put on a timer would i get 24hr 7 day timer and would this be a straight feed to timer then off to fittings???

cheers trev

Yes, I would put in a DP switch before the time just for ease of maintainance.

yh, i would put a fused spur(5A) as im tapping off somewhere.

does it have to be 7 day timer??? i was thinking maybe just 24hr one, as he can change accordingly to suit morning light and evening.

would one of these time clocks have an overide like with a central heating timer// any links?? ty

Think 24hr would be ok. The simple immersion heater Timeguard type have an override.

yes fuse spur with timeguard timer fitted many 7 day one might be better gives you more options for lateron dont think there that much dearer

24hr timgeurad .... Note: TS900 & TS930 Not to be used with fluorescent or low energy lighting. Can be used with filament lighting up to 400W. Cannot be used with discharge lighting (e.g. SON and Metal Halide). ETU2000 & ETU8000 can be used with up to 500W of fluorescent or low energy lighting and up to a 1hp motor. Can also be used with up to 2500W of filament lighting. Cannot be used with discharge lighting, (e.g. SON and Metal Halide).

any directions for the no hoper here ..

Socket Box Timer

I have used these timers for MH lights or Sons, they are not pretty and the 7 day increments are quite large but have been dead reliable and pretty cheap.
Tried the timeguard digital ones and the display was too small for my eyes. There is a manual overide although quite small button. I have found most of my customers can handle setting these up. However they will loose the time if it is switched off so try not to them use the FSU as a switch.

cheers plugs and sparks.... and are these l-n-e in and out too lights. id go with the older one as less chance to go wrong

yep, it needs L and N to power the little clockwork timer and has easily identified NO timer contacts. So LNE in and timed L out, all done in terminal block.
Have put in around a dozen of these.
The link has the wiring diagrams, i have never used the digital version which looks more delicate. They say not to be used for discharge lighting but i have used them for small MH units like you are thinking off. Worst case you have to drive the lights of a contactor driven by the timer, Sq D do a nice beefy 20A contactor that has the umph to make and break discharge lighting if you need 600 + watts etc..

would these pull a big surge currrent, possibly tripping circuit breaker????

 

[plugsandsparks]

Bigger than fluorescents but 3X150 is not huge, depends what breaker you are using. Generally i put them on Cs often C10s or C16s for the small ones

Just a though...What about installing a photocell, this would allow the timer to be set for example 4:00 to 11:00, but the lights would only energise when it went dark. It would save wasting energy with lights on while the sun is still up.

why dont you put the lights through a contactor then you can use the timeguard timer??

 

[i=p/u]

never wired a contactor before. haha aint got a baldys

 

[Kev2632]

the contactor will take the load of the lights use the timeclock to power the coil of the contactor
