  2. question about installing a GFCI outlet in a bathroom

    General Electrical Discussion
    I have a finished basement with a bathroom. I am looking to install an additional light over the shower/tub area with its own switch/outlet. Since its a bathroom, I assume I have to put in a GFCI outlet of some kind. Luckily, the wall where I want to install this switch/outlet is adjacent to...

  4. Anyone recognise these Occ Sensor/night light combos?

    General Electrical Discussion
    A friend has seen these switches in hotel rooms and asked for identification to possibly buy them: The Occupancy sensor activates the little nightlight built in to the switch (the on/off symbol). Toggling the switch turns the room lights off and on. Anyone recognize them?
  5. Cost effective wiring for a switch on an 850' run.

    Residential Electrical Forum
    I've been trying to figure out how to wire a switch to operate the lights at my front gate. I have constant power at the gate, which comes in on 260' of 12-2 copper from a sub panel. (I haven't laid the wire yet, so could possibly go up to 10-2 if you guys think it's needed.) My house is another...

  8. Induced Voltage

    General Electrical Discussion
    Hi guys & gals, I have a question about induced voltages (I think). We were taught that the main reason you run hots and their associated neutrals in the same pipe is because it cuts down on the voltages induced by the phase wires. You need the neutral there to prevent heat from building up...
  9. Switch Location Requirements?

    NEC Code Forum
    Is there any requirement in NEC which states we must, in residential wiring of lighting circuits, place a switch at every entrance to a lighted space? I've been told by my instructor to look up whether or not such a code reference exists, and I'm not finding it. Does it exist?
  10. Infinite Switches (240VAC use for 110VAC)?????

    PLCs, VFDs, Motors and Controls
    ok so in depth my question is can you use a 240VAC infinite switch like the ones on the stove on 110VAC provided that the load of the 110 circuit does not exceed the original (1500W in my case) application??? What would be the adverse effects? Would it still trigger the bimetal stripe? Would...
  11. Switch design

    General Electrical Discussion
    I need to switch from charge and discharge when the cell voltage reaches 2.7V, but the current is constant each of them last 30s or so. The current is 30A so the manual is hard. Can any one give me some advice to switch automatically or safer??

    Lighting Design
    I was just thinking about lighting for a building I am planning to build. There is only going to be one entrance and I am planning on having a lamp on all the time when unoccupied for security. Have any of you ever used a 3 way switch to control the single lamp and all the main building...
  14. 3-way and 4-way circuits

    General Electrical Discussion
    I have some friends who lost their house several years ago to a flood. After rebuilding (and a little re-designing), they had an L-shaped hallway that had 2 light fixtures operated by 3 switches, one at each end of the hallway, and one at the "L" which was added in the re-design. The...

    General Electrical Discussion
    Hey I'm new to this website and have a few quick questions. I'm wiring a potentiometer into the circuitry for a heated snowboard boot I'm designing. I'm just curious how you calculate the maximum current and voltage you can run through it without frying it. I'm using 6 3.7V 1500mA lithium-Ion...
