    To earth, or not to earth, that is the question.

    Due to boredom and a severe lack of friends to socialise with, I've decided to try making my own mains cable. I have a few questions to ask before electrocuting myself:

    Should I terminate the earth wire? Almost all my kit is unearthed. I've never understood why this is, but assume there's a good reason for it. The cable will eventually be connected to an a/v switchbox.

    Will using a russ andrews telefunken to IEC adapter negate any benfits achieved by using this improved mains cable?

    Is there any point terminating the earth if its going to be used with 2-pin telefunken kit like the switchbox anyway?

    Cheers,
    DT

    Only 11am and I need a :beer: already :laugh:

    Depending on the safety class the equipment does not need an earth wire, e.g. when the power supply is sufficiently isolated or entirely encapsulated (like in toys).

    No point I rekon.

    If the equipment has a 3-pin AC connection then you must terminate the earth wire however. :lesson:

    Edited the above as I forgot the "not"

    Also if you are using shielded mains lead you should terminate the shield to earth,to act as an RF drain supposivley,I did this with a load of Belden stuff see the TNT web site for some interesting reading.

    OK,

    All done. It was an absolute nightmare and I'm never making my own mains cable again. I'll gladly pay Russ "500% mark-up" Andrews prices!

    2 reasons for this woe:

    1) The cable itself was extremely unwieldy - the plastics used were of the hard, brittle type and completely inflexible. Should have used that LoRad stuff instead.

    2) The 320i Wattgate screws simply didn't want go in (the ones that hold the case to the connector). Tried as hard as I could, to no avail :(
