• OT: Electrical Supply Switchboard - what is "24hr Supply T.C."

    From Java Jive@java@evij.com.invalid to uk.tech.digital-tv on Thu Nov 20 12:34:06 2025
    From Newsgroup: uk.tech.digital-tv

    Until just recently I used to have an electrical supply meter which
    controlled my storage heaters & hot water via a remote wireless signal,
    a service which is being discontinued, so now I have a smart meter.

    Today I was examining the labels on the switchboards to check how the
    wiring is laid out around the house, and I noticed on the (formerly
    remote switched) heating/hot water switchboard labels reading ...

    Water Heating 24hr Supply T.C. Storage Heating

    ... which of course have the relevant circuit breakers below. The
    middle label has underneath things that are human controlled, the
    shower, bedroom heater panels, etc, so "T.C." can't be "Timed Control"
    as I first thought. A Google search threw up literally nothing. Can
    anyone here enlighten me as to what T.C. stands for?

    IrCOm not sure I entirely follow your post, but why not Timed Control? If the output of that breaker went via the Teleswitch it would indeed be timed control.

    Because the appliances in that section - immersion heater override,
    shower, bedroom heaters, etc - are not under timed control, they're controlled by the occupants of the house, see:
    <www.macfh.co.uk/Temp/Mains_Switchboard_-_Timed.jpg>

    There are three sections labelled as above and also as A, B, C ...
    A circuits - Storage Heating (timed control)
    B circuits - 24hr Supply T.C. (human control)
    C circuits - Water Heating (timed control)

    (Note: In the photo, the immersion heater is currently not connected
    because of ongoing work in the bathroom.)

    Some sort of "Circuit"? These labels appear to be standard with "L"
    numbers so perhaps look for an old Wylex catalog? Why on here? try uk.d-i-y?

    Found this from 2013 which contains models of consumer unit very similar
    if not identical to mine, but none had labels like mine ...

    https://www.voltimum.co.uk/pdf-catalogues/wylex-product-catalogue-2013-domestic?page=3

    I suspect the labels, although they are probably official as I think you
    are suggesting, were installed by the electrician setting up the system.
    It seems to me therefore that I'd have to find a catalogue or printed
    book of the labels themselves. It does seem odd that a search found
    literally nothing.

    Why on here? try
    uk.d-i-y?

    I gave up subscribing to that ng a long time ago because it was too full
    of right-wing political BS and the actual d-i-y advice itself was either rather obvious or else when it wasn't didn't seem to be very useful; to resubscribe now would mean wading through a load of back posts. While
    I'd like to solve this little mystery, I can live without knowing the
    answer if I can't.

    It's not so bad recently, and Adam (ARW) has been revisiting so you'll
    get an electrician's input. Anyway, all you need do is subscribe,
    download a few posts, ignore them, then make your post and see what
    comes in as replies.
