A different RCD problem.....

    Couple of years ago we bought a new raclette grill from Lidl (swiss/french cheese thing, yum yum).
    It works just fine except it has a very simple thermostat which causes the main RCD in my distribution unit to trip every time the grill thermostat 'cuts out'.
    The only way we can currently use the grill is via a 15A extension reel to the garage. The distro unit in the garage is not affected by the grill thermostat and the 'heath robertson' arrangement appears to hide the grill from the main RCD.
    But it's not a particularly elegant arrangement and not recommended when raining! So my question is, is there a plug-in solution that might 'hide' the grill from the RCD and allow me to clog my arteries safely?

    It's probs got Some earth leakage, when added to what ur other appliances are leaking, it's added effect is causing the trip out.you could have it tested but is it worth it.

    not really. Get it pasted, but that wont help you. Buy another one

    maybe a plug in rcd before the grill plugs into the wall socket (as this should trip before the one in the consumer unit if it plays up) maybe get a pat done on it to get to the bottom of its issues

    Well a plug-in RCD might help with me running down to the distro box in the cellar every time the grill gets up to temp, but I'd still need to sit there resetting it.
    Shame to bin the grill.

    your only option would be a new circuit on a non RCD circuit. It would need to be into conduit or more than 50mm in the wall both sides. Then hardwireto it into a spur.

    What makes you think that?

    Yeah, this is a tabletop grill which gets used 3-4 times a year and definitely not worth a dedicated circuit. Portable genny? :)

    Obviously it may not, any other words of advise that may help the OP Mr Risteard?,instead of ridiculing others suggested answers, just saying:rolleyes:

    Well it was a flawed claim.

    For good advice, certainly - the OP should get an Electrician in.

    Agreed, although we could all be more 'accomodating' on a public forum, which by its nature is here to attempt to assist the public on a public forum, ad infinitum:cool:

    into conduit or more than 50mm in the wall both sides ----

    Or surface run.

    As it appears to be the thermostat switching that is causing the problem you could try a plug in mains filter or filtered socket. In general they are intended to prevent inerference getting into the appliance from the mains, but in this case it may be enough to work backwards.

    A new circuit just for the grill ain't worth it.

    I would also be concerened about the box in the garage masking the problem. Sounds like it isn't RCD protected.

    Kind regards

    indeed seneca either wayto wouldnt take much depending on location ect. But itto comes down to is it worth it

    im now a trained pat tester and from what i have lernt/ found most plug in rcd units (either plug type or plug through type) are desgined to be slightly more senstive to faults also when an apliance fault and the fact they go between the appliance and the outlet then by design they should trip 1st however doesnt mean it always will

    and as it seams to be faulty appliance its a person with a pat machine (that will be best suited to help) as this will be able to carry out a battery of tests that should get to the bottom of what is causing the problem

    Thats just not true. A 30mA RCD is a 30mA RCD. With two 30mA RCDs on the same circuit, there is never a guarantee which is going to operate first. Even two identical RCDs can have slightly different characteristics.

    most plug rcds have a 40ms trip speed.
