Light Keeps Killing Timers

280 posts in this topic

I think many growers have gone through the initial stage of thinking its OK to not use a contactor. Given the fact its a safety issue, why take a chance?

 

Its not as if contactors are that expensive and its worth it just to have peace of mind. I have had mine for a long time, don't even think the company is still around, but the contactor sure is.

Its not a safety issue, its an inconvenience issue. A timer with welded contacts should not pose any safety risk at all

It really is a safety issue they don't always weld shut they often start to oxidise and then thermal runaway occurs. 

Then your house catches fire!

It's the inductive load that's the issue. 

Just think about it we don't sell contactors, why would we make this stuff up? 

A decent cheap timer suitable for upto 2 600w hps lights as it has a small contactor built in, is the black orchid available from £10 on ebay. Cheap and safe.

Can anyone recommend a light friendly RCD? What contactors do you guys use

 

By the way, I currently use 1000w on my heavy duty timer I bought online from ProGrow, it's rated 3150w and it's lasted years.

Hi

 

I am looking for advice on a suitable timer for 450W LED light that I can put on a 18 6 daily programme?  Is it just as straight forward as plugging in setting up and switching on?  I wondered about these?  Any advice please?

if you dont want to get a contactor, get a heavy duty timer for a £10, theyre rated for using upto a 600w hps (I know your planning to uuse a led) & are more reliable than grasslin or digital timers.

LED's don't start up as heavily as HID lights but Still go for a heavy duty one anyway though. Those kind of ones should not be used for inductive loads like grow lights especially HID ones.

yes theyre called heavy duty timers, maxibright have just brought out their own version & is black, the other heavy duty timers are a whitish cream colour & are the same thing.

 

one thing though, theyre a bit wide & if your socket doesn't have a on switch, the timer will block the next socket.
