    I had to buy a pushmatic 50A breaker not to long ago, none of the electrical supply stores in my area had them in stock so I just bought one off Amazon with free 2 day shipping, just figured I'd let ya know in case you go that route...

    Thanks for all the help. I had an electrician I know over to look at everything earlier. Looks like I need a few upgrades to do this the right way...

    hello i have a electrical question about wiring an exhaust fan to a thermostat and a cycle timer,
    ultimately i am looking to have my one fan, exhaust air during the day hooked to the thermostat, but when lights go out and the temperature drops to the point that the thermostat stops coming on i would like the fan to come on say 5 minutes every half hour. this question has been asked before, and the consensus seems to be adding a transformer, and relay to separate the circuits. My question(s) is/are, could i not just hook up the thermostat, and timer in parallel to the fan?, would a backfeed of power into the thermostat and/or timer really be an issue? alternatively i have considered hooking the thermostat and cycle timer to the fan and just have the thermostat and timer each hooked up to a timer that would have the thermostat circuit live for 12 hours of the day, and the cycle timer the other 12 hours, but then i am dealing with a backfeed of power into whichever timer is off while the other is on, would this be an issue?

    i hope that is as clear as it is in my head, i am a mechanic by trade but not an electrician, a/c still eludes me a bit and would like a second opinion

    I need to run 2 inline fans at half speed. I have the 2 fans and the two timers but only one fan speed regulator. Any reason I CAN'T:
    1. Plug fan speed regulator into the wall
    2. Plug a power strip into the regulator
    3. Plug in 2 fans on 2 separate timers, running on different schedules, into the strip that's already "dimmed" by the regulator?

    Thanks!

    What is the regulator rated for? and how much power are you pulling with the timers and fans? So long as the timers and fans do not exceed the rating of the regulator you should be fine

    Thanks for the response. FYI everything is UL listed. The regulator is a Speedster, 120 volt/15 amps. The 2 fans are both pretty small, 4 inchers. Both run fine at 50% (unlike my inlin duct extender), I just didn't know if the 2 different loads would tax the regulator in some way, since they'll sometimes both be off, or both be on, or one off and one on. Thanks again. :eyesmoke:

    I don't recommend you installing a thermostat & timer in parallel to your fan. For one you would have to make a custom Y cable that plugs into both. Secondly if something malfunctions, which happens you got problems. Just saying..., depending on where you plug the timer and thermostat into you could potentially have 240v where expected 120v should be. Theoretically speaking if timer plugs into 120v L1 and thermostat plugs into 120V L2, if you get a "backfeed" you got 240V. That's literally playing with fire. Also having a transformer is out of the question bud. Don't believe everything you read. Not sure if you're familiar with the product Flip Box but you're are essentially trying to make a ghetto rigged Flip Box. Here is my suggestion for you. Buy another fan and run it on a timer to turn on during lights off. Then use the other fan #2 with the thermostat during lights on. Install backdraft flappers on both fans and you will be fine. Don't try to do things cheaply or in an unorthodox manner when it comes to playing with electricity otherwise you're eventually going to pay the price. my 2c

    The regulator essentially reduces overall power to slow your fan speed down. You're timers that are plugged into the regulator power strip may not be able to turn on with such low voltage coming from the strip. That's the only thing I can think of. But should be an easy and safe test to check out. GL and let us know if it worked.

    So my friend just had an electrician friend over to finish wiring his shed up. Nothi n g to crazy just a hidden type room inside the shed. All insulated and walls up. Wire running outside of wall instead of inside.
    My question is, he just sent some pics of the "finished product" and they didn't use conduit.. having wires run along the wall with no conduit is a no-no, no?

    I used metal sheilded conduit on the inside of my walls, I cut 0 corners..

    Him having no conduit, is it a big enough problem that I need to show up at his house with conduit and a 6 pack and convince him to fix it?
    I was baffled when I saw it... he said it gives you more room this way.. hmmmm? Lol
    Maybe I'm retarded, figured I'd get some advice from someone who knows much more than me !

    Is it to code? No it is not. But if he does not plan on moving out anytime soon and is okay with the way it looks and it works how he wants it to then I see no problem. Did they use Romex (plastic insulated wire)? or metal shielded wire? metal shielded is a little more safe since it has more than just plastic wrapped around the wires, it is out of the way? like running in the corner of the wall and ceiling? There a quite a few factors to consider, usually conduit is only used when running coated individual wires. Best practices say to ensure that nothing can damage the wire and cause problems, but some peoples wallets say get it done with the resources I have given you. I am sure that this message has given you more questions than answers, ask away and I will help you the best I can.
