UK Electric Hob Diversity.

ZippyMo · Apr 1, 2020

Hi colleagues

A friend of mine has purchased this electric hob for his kitchen.

BHII6015_BK | Baumatic induction hob | 4 zones | ao.com

This induction hob from Baumatic has 4 zones, a residual heat indicator, easy-to-use touch controls and a boost function. Order today, get it tomorrow at ao.com

ao.com

It shows on the spec that it has to be hard wired by a spark.

So after calculating the amperage (5400÷230), I'm getting 23.4amps.

Will diversity have to be applied just for a single hob? Or is it only for a cooker which includes 4 or more hobs, oven and grill?

Any help will be appreciated.

What do the manufacturers instructions suggest for the installation?

As above the MI will usually spec a minimum cable and breaker size...

Ok I haven't seen the hob yet maybe there are some instructions.

Just waiting for Mr Corona to get lost first though.

A quick search find a copy of its manual on-line, they say:

"This appliance must be wired into a 30 A double pole switched fused spur outlet, having 3 mm contact separation and placed in an easily accessible position adjacent to the appliance. It should not be located above the appliance and no more than 1.25m away from it."

Then they go on to say to use "H05 RRF 3 core x 6 mm" cable but I would be pretty sure the 07 rating is fine, for example:

Superlec 3CORE 6MM 6383P H07RN-F EPR / PCP FLEXIBLE MAINS CABLE - EN60332-1-2

H07RN-F Cable is a non armoured flexible mains and control cable designed primarily as a trailing cable for use in the supply of energy for portable or mobile equipment.The cable is Ideal for use with transformer pumps, welders grinders, temporary lighting cable and feed cables to heavy mobile...

As you say, looking at a bit of a delay just now...

Edited to add, found it here:

Just noticed its not exactly the same part number, so wise to double-check when you do get it. Odd that Baumatic's own service site is not listing that model!
