Oven cable size
29th August 2017 at 15:02 #1792718
i have a new oven to fit and taking the opportunity to add new cable to supply the power. I already have 6 mm cable but when I have unpacked the oven it has 3 wires at the back but they are 2.5. Before I biy a new cooker plug my question is do I need the 6mm cable?29th August 2017 at 17:44 #1792777
Do you know the wattage/amperage of your oven when its on full? There are not manny single ovens that will draw sufficient amps to need anything other than a 13amp plug, but do check to be sure.

Even if you were to connect a little oven, the French regs remain the same: in single-phase with 6 mm² and protected by a MCB of 32 amps to an oversized back box in the kitchen to feed your oven. From there as most French electricians do with a sortie de câble to your oven. Much cheaper and easier to fit in a confined space than a special 32 amp socket + plug. There should be a helpful sticker somewhere to offer you some guidance, like this one for a Siemens oven. If the manufacturer decided that 2.5 mm² for the last centimeters to the socket is the way to go, don’t you worry, almost no extra voltage drop.

Ah ok makes sense now, I have been looking at other houses who all seem to have the 6mm going to the junction
so just a sorte cable as you say with connections

If you are running an appliance with a smaller section cable/flex from a 6mm² supply you should de-rate the disjoncteur to match. In your case a 16A is all you need. This protects the appliance cable from potential overheating/fire.2nd September 2017 at 10:49 #1793393

Since when has a 13amp plug been part of French electrical regulations?
6mm cable to a cable de sortie is the way to go to comply with the regs, if however there is 2.5mm flex already attached to the oven, then as has already been said, down grade the 32amp MCB to 16amp.
If you think it is expensive to hire a professional to do a job, just wait until you hire an amateur.2nd September 2017 at 15:50 #1793411
Where would I find information regarding which size disj to use for all areas2nd September 2017 at 16:22 #1793417
Get a copy of “L’Installation Electrique” by Gallauziaux & fedullo the illustrations are superb and will give you all you need to know:

mikej – the document you linked to is out of date. It does not take into account Amendement 5 to NF C 15-100 (which has been in force since November 2015) & is therefore misleading in terms of the number of sockets allowed on a circuit, & in regard to bathrom zones (amongst oather things).3rd September 2017 at 16:27 #1793517
In that case it may be helpful to the OP to link the updated amendments, have to admit I did not check them to see if they where the latest, just thought it may lead the OP in the right direction on which disj to use where.
