UK Gas Cooker conked and electrical cooker replacement

[advicewelcom]

Hi, quick posting - welcome any advice as new to this stuff...

Have a Howden HJA 0150 gas grill/oven with a broken thermostat that and can't get a replacement (grill igniting but no gas coming out of oven burners when on).

The Howden grill/oven is on a ring in the kitchen which has following appliances on it:
-microwave
-fridge freezer
-kettle
-toaster
-a Howden gas hob
-the busted Howden grill/oven
-couple of kitchen sockets generally not used

It all goes back to a RCD with a fuse that says - MTN132 b32 hanger fuse

There is an electrical wall connection for the grill/oven, with (I think) a 6mm wire for the ring (and not the thicker 10mm wires used for showers).


I may want to replace with just an electrical gill/oven. So some questions...

-Is there is max kilowatt oven that I could just wire into the current wall socket (which is used for the current grill/oven electrical ignition connection)?

-Would I need to replace the fuse in the RCD for the main? And is so with what?

-Would these things ensure the fuse would not trip if the oven was switched on?

-There are lots of electrical ovens but the instructions say they should be wired directly to the fuse box, so wondering if there is one which can just run from this ring main (if I upgrade the fuse)?


Would hate to buy an electrical oven and then its a nightmare and expense to fit it (the fuse box is currently full).

Welcome advice.

It would be adviseable to get a local spark in to assess the wiring, considering you are changing to electric oven then calculatation of a load is required.just to add it may need it's own circuit.

Thanks. Some manufacturers indicate that (perhaps to cover themselves) - but I understood that below a kW level - the ovens can be plugged into mains.

If elecy works gets too pricey it makes sense to just replace it with a gas girll/oven (which is not the preference).

Would hate the fuse to be tripping everytime you turn on the oven.

Was hoping there was some sort of back of envelope calculation that could estimate the wiring was okay, the fuse just needs upgrading and the oven shouldn't be above a certain kW?

It's not as simple as that. The information in your OP has conflicting information where you mention the current setup is connected to the kitchen ring then, mention it's possibly a 6mm at the sw FCU. Without knowing what the true setup is then any advice given might be wrong.

I know elecy's like absolutes.

Had a pic somewhere - but recall the wire its tje one down from a 10mm v. thick shower cable. The stuff used for ring mains - think its about 6mm.

Will get it checked - but assuming 6mm - do you think its poss for suitable power electrical oven could be fitted with a suitable fuse in the RCD that will not nuisance trip?

6mm cable is not used for ring circuits. 'One down from 10mm' - are you measuring the outer diameter maybe? This is not how cable size is determined.

I would say it is time to get a sparky in. No shame in knowing your limits.

Hi, yes, I just don't wanna waste elegy's time to realise its just a case of bringing the right oven and fuse.

Picture of the fuse box wiring attached for the grill/oven. Assume its the standard burial type for house wiring.

Gas oven replacement easy like for like - but welcome knowing if its poss to get suitable electrical oven with suitable fuse in the RCD considering what's on the circuit?

 

[telectrix]

basically , if your new electric oven comes with a fitted plug, you can plug it into the ring. if not it will need a dedicated 32A circuit.for whick you need to get an electician.

You won't be wasting their time if you pay whatever is agreed between you and him/her to come out and take a look.

Hey thanks, much appreciated. And do you think I need to do anything with the MTN132 b32 Hager fuse in the RCD? Does that need to be upgraded considering the stuff on the ring to prevent any nuisance trips?

This is on the ring...
-microwave
-fridge freezer
-kettle
-toaster
-a Howden gas hob
-the busted Howden grill/oven
-couple of kitchen sockets generally not used

Maximum MCB for a conventional ring is 32A fed from an RCD of 30mA
(or vice versa) or an RCBO of both the above ratings.

You can't just uprate the RCBO/MCB, it's sized to protect the cable against overload and to disconnect in the event of a fault. Ring mains have other guidance too. Some hobs are advertised as being suitable for running off a plugtop but unless the instructions say the oven can some electricians might not fit it regardless to the power consumption.

 

[DPG]

You can't just increase the rating of it, no.

Please get an electrician in for your own safety.

 

[Avo Mk8]

If you add up typical consumption figures for the appliances you have, and include a new plug-in oven, it's not enough to trip the MCB.


1.7kW -microwave
0.5 kW -fridge freezer
2kW -kettle
1.2 KW -toaster
2.2 kW -a new oven
= 7.6kW = about 32 amps, depending on exact mains voltage
This doesn't include an allowance for the remaining sockets, where you say 'generally not used'

Although reaching the limit for the circuit, from a pragmatic point of view, will you ever have all appliances on at once?

Don't fiddle with your electrical installation.
As Tel said in post #8, just get an oven that is designed to be plugged in, and plug it in!

Thanks so much

This is the fuse (hanger is the manufacturer) and its looks 32A

Yes, plug in one seems fine - had to check as even if its plug in, was worried it could keep tripping the fuse if someone decided to make a cuppa and toast whilst chips were in the oven and warming some milk in the microwave. with phone recharging in plug.

...looks like there are options and hopefully they don't have any small print saying it needs its own line to the fuse box.

Just didn't know if anyone else was in this position and had a recommendation for an oven that goes in no hassle for reasonable price?

I assume its a case of stripping plug so its fit it into the FCU.

I would need someone to cap off and cert the gas supply I guess?
