a contactor is an 'adapter' of sorts. the timer switches the contactor on, so the contactor takes the load.... and yes you need to buy an actual contactor, and not a set of terminals

thanks again your input is much appreciated.

because that's not a contactor craig, thats a set of auxillary contacts... i.e. it connects onto the contactor to give some extra contacts, that switch control signals for a multitude of uses

hi scraglor thanks for the reply,so ill just have to buy a proper one then with the A1 and A2 terminals i guess. Iv also heard people saying u can use a normal plug in timer for a 250MH if its a decent one but iv tried four and they have all broke when it tries to switch of for the first time so i was wandering if i could plug an adapter in to a 10 amp contactor/relay that was bought from a shop. It only has 2 sockets on it and iv already got a 600 and a 400 HPS on it thats why i was wandering if i could have the adapter plugged in or is that just way to much for it? and thanks again for your help its much appreciated.

Think we may have some "crossed wires" here. The term "contactor" can apply to either an electrical component or a device incorporating a 24 hour timer and contactor component for switching HID lighting.

You currently have a 10 amp contactor device switching a 600w and a 400w lamp. Your 10 amp contactor device has 2 outputs, you wish to know if it can take the inductive load from another additional lamp by using a fused plug-in double adaptor to give you an extra output socket on the contactor device.

In addition you mention a 250w lamp but don't say explicitly that this is the one you wish to add to the setup.

My gut feeling is that you'd probably get away with adding the 250 but you'd be right on the absolute limit. I'll leave that to Scraglor and those who understand these things to run the numbers, because I really don't know for certain.

Personally I'd be inclined to spend £20 or whatever they are and get a second 10a contactor device. If you want to make your own incorporating a contactor component with the A1 and A2 terminals connected to a timer that activates them it's going to cost more once you add up the cost of all the bits you need to make one (you'll probably spend that £20 just on the box you get to put the bits in!) If you're up for the challenge and have some cash spare I recommend you make one. If on a budget I'd just invest £20 and sleep peacefully at night.

Peace

Hy there guys..
Back again with contactor questions... I was hoping Scraglor or one of the other electrically minded chaps would would give an opinion about a contactor.. The Chint NC12508U5. Its a 4 pole 2no/2nc jobbie... Basically I would like to know if this is suitable for flip/flopping HPS. If you search chint lighting contactor on google uk, expert electrical has the pdf with all the tech details.
I managed to snag a telemechanique LC1D09 second hand for cheap, but Im still looking for more.
Hope everyone is doing well and feeling good.
Thanks.
