Extension cords, powerstrips, the plug in outlet extenders.... They all run a risk of catching fire, depending on the wattage going through them.

From my understanding, it is best to use a relay via a timer or environmental controller to cut the power to high amperage devices such as an HPS. How does one cycle the ballast before cutting the power to it? Is there a way to create a very safe power strip? Quote:

Yea, plugging a timer into a powerstrip and then having a small cord run to a relay with your main juice in the relay box is the best way to do stuff like that.
Someone posted a DIY on that not too long ago and it was very well built. Wish I could find that link again... What do you mean by "cycle the ballast"? Are you flip/floping or something?

Anyway, get a double gang box and some good-quality 15 amp receptacles and wire it all up with #12 wire and a good cord end and you have a good quality power strip - not real pretty, but good quality. If you're just going to be running small stuff with low current draw, you can use a three gang box and get six sockets. ...or you can install one switch/receptacle combo and switch the receptacles. Use pigtails coming off the incoming line and neutral to wire your receptacles - then it won't matter what's plugged in where. Be sure to install a cover plate of some kind. Use the shortest amount of cord that you think you can get away with. Don't get unsafe in this pursuit, but, the shorter the cord the less the current drop, so be reasonable. If you think there might be moisture issues - which there really shouldn't be with electrical stuff, but... - use a waterproof box and fittings for your assembly. PC |

I just bought 2 WH40's for 20$ each @ home depot they are changing over to GE so they were on clearance.I want to run 4 1k's per timer.I looked for 240 volt duplexes but couldnt find those, only a 240 v simplex.I take it they dont make a 240 duplex?Can someone show me wiring diagram for 4 240v simplex coming from my WH40 please?Thanks

Hi MADPENGUIN may i use s.s.r.(solid state relay )instead of using mecanical one for switching HPS.
In 120 volt i know i have to open the hot wire (black)but with 240v 2 hot wire do i need 2 s.s.r. ? S.S.R. will be rated at 40 amp at 240v. with cooler . i will drive 2 1000 watts ballast.

I did remember something that I had typed the first time, that I forgot to retype the second time... Let's say I have a circuit with several receptacles and only receptacles. on a single single breaker. Can a single receptacle on the circuit handle the entire recommended amp load (80% of total rating) or do I just see what gauge wire is connected to the recceptacle to see if it can handle the recommended max load? Thank you so much for the information and patience. When I look for an electrician, I certainly hope I find someone who takes as much pride in the craftsmanship as you do. PharmaCan - Hey thanks a lot. I suppose I should match the gauge of the wire in the "power strip" to the gauge of the wiring to the receptacle (at least) or do you recommend something. Dr. Conjuror |
