Terrible kitchen install

[stuarth]

Went to do a report on a kitchen install this morning and it was bad from start to finish, badly fitted units, not installed to the plan, badly tiled floor etc
on the electrics the electrician apparently dose not carry a spirit level

but the thing that worries me is the 16 amp oven wired into a 40amp switch straight back to a 32amp mcb won't the oven flex be rated to 16amps there for a fire risk when its on a 32amp mcb under fault?

Do you mean more like this;

is that robin hood, or gender neutral SWD in drag?

Dunno, never been round to his house

If the oven incorporates a fan and other gizmos then it is not a fixed resistive electrical load. You need to consider also the cords capacity to carry fault current.

But in the event of a short circuit fault there will be very little difference in disconnection time between a B16 and B32. Having said that I'd probably put that circuit on a 16 or 20a MCB- unless the cooker isolator had a socket on it.

They don't always come with a flex; just instructions to consult with a competent electrician

Yes I know this but was commenting within the context of this thread.
Every unflexed oven gets a 2.5mm 3 core H07 flex with me.

there you go with the negative waves. adding a socket complication,

 

[Dave OCD]

You can never have too many sockets !

No comment, he might start talking about ducks again.

might not be fixed as in it's variable, but it does have a finite max. load, so can be considered as fixed.

Fixed loads should be purely resistive, a fan oven is not a fixed load.

Thousands of others wouldn't.

what about a shower then? modern ones have electrinocs in them.

But its a teeny weeny fan of no significance.

And some even have electronics !
