DIY Power Strip Help


Hi, first post, but have been lurking for long time. I am trying to design a power center for an aquarium stand, and have an idea, but dont know if it would work, or how to go about it. Any help would be great.

What I want to do is have a panel on a side door in the cabinet, with 6 to 8 light switches (illuminated), and have each switch connect to an individual outlet on the inside of the cabinet. The whole thing will be powered by a plug going into the wall outlet, for quick easy removal.

One other thing I would like to add is a spring wound timer, but have it reversed, so when i set it, it turns off power to a certain outlet for the duration, and then turns back on when the timer is done.

Again, any help would be great. Thanks.

That's all pretty easy. The only part that is somewhat complicated is the "reversed" timer. Unless you can find a timer that works that way already, you'll need to use a relay. In order to save space, I would probably choose to use dual switches (http://www.amazon.com/Leviton-109-05...dp/B00004YUJ3/). You can fit 8 switches in a 4-gang box that way. On the inside, you could either use two 4-gang boxes for 8 duplex receptacles, or you could split the top and bottom halves of the receptacles and use only four.

For the timer, you need a relay like this one: http://ribrelays.com/Products/Power-.../RIB2401B.html You connect the relay coil to the timer, and then wire the receptacle through the normally-closed contacts of the relay.

Man, the fun I could have making all that work with an AB Pico relay.

Such timers are available !
They are used as control equipment
I think they call them "time out timers"
Or at least we Aussie's call them that,
You Americans might call them some thing different.

You will have to visit an electrical supply house for these
Don't waste your time at HD.
go to where electricains buy there supplies from.

Sounds more like a grow-op setup, not an aquarium setup.

The reversed spring wound timer is to turn the pumps off during feeding time, just an insurance in case I forget to turn them back on.

Sounded like an aquarium set up to me.

Yeah, ditto on the reverse spring, could even us that for the "night light" part of the refugium... Use a standard SPDT relay to flip between 2 things with 1 signal, i.e. the feeding signal from the timer comes on, triggers the relay to "open" which shuts off the pumps, and when the timer turns off the relay goes back into "Closed" state. The people at ribrelays are great, I have a similar issue I was trying to find, and these are all prepackaged for normal use, just get a metal J-box and wire up.

http://ribrelays.com/Products/Pilot-Relays/RIBU1C.html

Of course he could be using the reverse relay to turn off the fans while he injects CO2 there are plenty of questions on these forums that are suspicious, usually it starts with "I want to power 2x 400w heaters" what size wire can I use to pull power out to this remote shed...
