Electrical switch issue
In the kitchen I have an MK Grid Switch this has a nice neatly labelled
switch for each of kitchen fixed appliances. The Oven (not hob) is a 20A DP switch and is fed from a dedicated 20A radial cct on 4mm2 cable Grid switch feeds to an MK5045 cooker wiring point Oven is being replaced with a Neff U1ACE2HN0B and information is that it is rated at 5.9kw ..... which to me says 26A I can't find a Grid switch higher than 20A ..... I know I could increase breaker to 32A ... but would then need higher capacity grid switch Anybody any suggestions ? So far only thought is I would need to put a link in bypassing the GRID switch (and fit a blanking plate) and put a DP cooker switch instead of MK5045 connection point. Unless anyone else has a better idea. If my idea is the option what in neatest way to 'bridge' the 4mm t&e ... use WAGO lever connectors ... https://www.tlc-direct.co.uk/Products/WA412.html They are good for 32A or WAGO push connectors rated at 40A https://www.tlc-direct.co.uk/Products/WA412.html Anybody experience of using these ? which is easiest to use ... or is there a better way Connection will be within confines of the 'back box' so all still protected. |

The 2nd product code link should have been:
https://www.tlc-direct.co.uk/Products/WA173.html Not used either so unsure which is easiest to use. |

I suppose you could use the existing grid switch to switch a contactor or relay, and have that switch the oven.

Connection will be within confines of the 'back box'Â*Â* so all still protected. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Its not like heating of cables which is averaged over time its an instantaneous event. Not only that, for a fixed appliance like an oven, double pole switching capable of proper (i.e. = 3mm contact gap) isolation would be appropriate. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

(still don't fancy a ~6kW load on it though!) -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
