induction hob and cooker circuits

[quote="Steve";p="151120] How often will all the cooking elements be ON? How often will this happen when the shower is on? And any electric heating (if storage, never)? How often will this add up to 150A? (a 100A 3036 will pass this for over a minute, nearly 2)
[/quote]

It doesn't have to happen often to cause a major nuisance, once is enough if it blows the service fuse.

If a family is staying in the property the chances of the cooking, heating and shower being on at the same time is very high IMO.

It would only take a shower to be on (45A), kettle (13A), cooker (25A w/standard diversity calc) and just 4kw of heating to take you over 100A.

Granted, this won't blow the main fuse but having all three electric cooking, heating and shower makes it difficult to calculate/justify the maximum demand number for the certificate, and that's assuming a 100A supply. ;)

Hi Skenk

You are quite right about the accessories of course, but the quote was excluding plastering etc - currently everything is accessbile, ceiling down, walls easy to chase, etc etc

Helpful comments so thanks
