Massive cooker cables - how to terminate
This is more theoretical at the moment.
When the kitchen is tiled, I'll be fitting a 90cm wide cooker (induction). Looking at some idly in the shop, I noticed a Smeg (probably not a brand we'd get) - or more particularly, I noticed the cable hangling out the back. It must have been getting on for 15-20mm diameter! The conductors looked like 6mm2, maybe 10mm2 - but it was a rubber cable (H07 type possibly) and having checked some tables, 6mm2 would indeed be about 15mm OD, and 10mm2 20mm OD. How on earth do you terminate a 15-20mm cable? That would be way outside the capacity of a standard cooker connection plate surely??? |

You might need pliers to bend the conductors if the space is tight. And need to be carefull cutting to the right length. |

I've had to repair 3 Smeg ovens a number of times over past 10 years. Their internal cable harness and swiches burn out - a thoroughly unsuitable design for longevity of high current wiring. I would never buy a Smeg appliance which used electricity for heating. A Smeg gas hob with just electronic ignition has been OK for years - only had to repair the ignition circuit after water poured into the cooker after a carpender put a screw through a heating pipe, but that one wasn't Smeg's fault.

How on earth do you terminate a 15-20mm cable? That would be way outside the capacity of a standard cooker connection plate surely??? A good quality cooker cable outlet should handle it. I fitted a Hotpoint induction hob recently, which had a similarly fat cable. However, it was about 6 conductors IIRC, for connecting to several different types of supply and balancing the load across 3-phases, split-phase, or for just using single-phase. The multiple conductors came crimped together for single-phase - you needed to cut the crimps off and redistribute the conductors for other schemes. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

I've seen that multiple phase arrangement, but in the cooker side junction box (where you supply your own cable). I was just curious at the massive cable lying around the back of the Smeg in Currys - looked like something intended for a Vax 8600! |

Even so, 4 rings and an oven can't be much more than 6 kW without diversity. Owain |

I would never buy a Smeg appliance which used electricity for heating. When we moved in 5 years ago there was a Smeg washing machine and dishwasher here, which were already 3 years old. We haven't had any problem with either of them. The washing machine even survived me ripping the power cable out of the back of it (electricity was off, fortunately) a couple of years ago! -- Jeff |
