Using a 6mm T&E to feed a Ring Main

[Engineer54]

Question 2. There is also a single 2.5mm radial from the consumer unit (16A MCB) to the Kitchen area (was an old storage heater I believe). Cable is run the same way as above.
Is this likely to be sufficient if they install a simple 600mm wide built-under oven and electric hob?
What about changing the MCB to 20A?
Any thoughts?
Thanks.

There is no-way a 16A or 20A radial circuit on 2.5mm T&E will cope with both an oven and a hob!! So you had best get a 6mm cable in while you can, to supply these two cooking appliances!!

Hi, this came up in professional electrician a few months back - they referred to it as a 'hybrid ring circuit'. The outcome was that it was perfectly acceptable. Useful it rings are to be controlled via contractors (I.e emergency stops ect)

Any circuit that isn't classed as a standard circuit, is classified as a ''Hybrid''.... Lollipop rings have been around for donkey's years!! lol!!

Its often referred to as a lollipop circuit, not that you would find it in a regs book.

Sometimes its the only way to work and thats to "adapt" a redundant cooker ciruit so if the dead readings are good and under the max for the MCB whats the issue - except how do you fill out the EIC?
