    Conductor and Component sizing

    My "text" would be just an UGLY's book. The allowable apacity of 4AWG wire is 140Amps.

    Conductor and Component sizing

    Hey guys, I am trying to put together a project but have hit a few bumps. The basis is I am running a 75hp motor with a soft starter that is 460VAC, 3ph... According to my text, the conductor size of the motor must be about 25% above rated amperage of the motor. I calculated about 96 rated...

    Motor Contactor

    I am selecting a contactor for my motor using Fuji. I need to know what amp rating to use. I have full load current, locked rotor current and no load current.

    Overloads

    I have a 3 HP three-phase 480V squirrel cage motor. I have selected a sz0 motor starter and have never had much to do with component selection. I have a control transformer size 75VA making my step down from 480-120 for my controls. I am trying to size some overloads for my motor starter and...

    Coils

    WEG TEFC(IP55) my fault - 3HP motor full load current 3.9A Loacked rotor 30.8A No load - 1.75A All based on 480V numbers

    Coils

    1/2hp motor. I am trying to size my transformer.

    Coils

    I am doing part sizing and selection for a circuit of mine. Was curious to how much current if any a motor starter coil will pull. It controls 480V 3 phase squirrel cage but is 120v controlled

    Relay

    Or will the fact that the switches open close the contacts, thus allowing current to flow through the indicator lights?

    Relay

    The relays are needed to control the indicators. If you look above you will see a temp and level switch that act as a shut down switch before the actual start/stop station. These are kinda the same thing, but they are another set of switches that control the indicator lights as far as for a...

    Relay

    ok, this is the last version I have saved. But the certain lines i have discussed have not altered. Bottom right corner is location if indicators.http://files.engineering.com/getfile.aspx?folder=e9e7b6ce-861b-4022-8ec3-2aae748e0bc7&file=Project_(Cody_Jenkins).pdf

    Relay

    My fault. I gave you the wrong information. I have a relay to be in series with a temp switch that is showing NC on the schematic. After the relay coil, the circuit is completed meaning there are no more components. I am trying to get this relay to switch on an indicator light when the temp...

    Relay

    Ok, I just graduated with an Instrumentation Degree and got hired on as an I and E Designer. I am working on a hydraulic schematic and trying to get some indicator lights wired off of a relay that is controlled by level switch or a temp switch. How do I do this? Keep in mind the voltage for...
