Powder coat oven keeps tripping mains rcd all off a sudden?

adamfromayr · Dec 3, 2018

Hi

Okay my powder coat oven i built was fine until today!

I had it working kept on for more than an hour etc

Pretty pleased with it all

2 x 2000w elements fitted and then wired into a 32a blue socket to the 42a isolator switch

But today its started tripping i looked insid emy control panel and all looks good and heating elements heat up maybe for 2 mins, then trips my mains rcd

I was guessing damp weather? condensation or something? as was working okay and for no reason today starts tripping all off a sudden? any idea guys?

RCDS are tripped by current leaking to earth. MCBS are tripped by overcurrent or short circuit

ah ha

So you think my earth is leaking? on my oven somewhere?

Not necessarily the oven. As I say there are many other things fed from that RCD. Could be anything on there, including wiring / junction boxes etc.

Disagree dude, As only when the oven is switch on it trips!

I admire your versatility, building your own unit but I'm afraid, judging from the your posts, your electrical knowledge and experience seems extremely limited.
Safety problems abound....and that's without seeing internal connections, etc.
It really is frightening that things like this exist as part of a domestic installation, without a true and proper design system.

Dam , Just had on for 5 Mins then Main RCB went again!!

Tomorrow when its brighter i will try One element at a time, though both are heating up okay for 2-5 mins then WHOOP RCB Switches off!

Im using all 32-40a Circuits, Only that OVEN Wire looks very thin, but its meant for oven use? but all my other cables are much thicker

Does anyone else have any good suggestions in what is wrong here??

Why not pay for a lowly electrician to come and sort it out for you at the fraction of the cost of a single box?!

JB = junction box, btw.

Can you power up the unit on its own with nothing else drawing any power?

Also the flex to junction box to singles floating and not attached or not protected is not a great idea.
