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

[MFS Electrical]

I know i asked for help but i think its doesnt have to be covered as im using special oven high temp cable and crimps, all the photos on google on inside ovens dont have anything covering the crimps and oven cable they are always left bare, so im not covering the ends in anything! the cable i will cover in high temp cable outer sheath from high temp cable ive got, i think if i make sure the new armoured conduit going into the base of my oven and up to the first element is 100% dry free and i cover the elements in a steel grill im going to be okay! Will also use silca gel pouches in the steel box section where the cables run

Hopefully that will be that

The box section will be holding far more heat than in the back of an oven the temp in that box section will continue to heat up and exceed the rating of the cable you probably need vents and perhaps a fan for that box section to keep the temp down

Folks call me pedantic...

CONDENSATION later becomes condomsensation...
the former occurs when, say, a hot steamy air mass hits a cold surface...
the latter? I couldn't possibly comment...

Think you definitely need to check element connections, JB connections, also what size is flex as it looks like it's feeding both elements

When you say you've "checked the cables" have you done an insulation resistance test to earth? Or have I missed something..

Hey You Guys!!!!!!

Okay as promised im Back no i didnt fry myself lol

Okay you guys, went and did it much better, My big mistake is bringing in the feed in from the side and down a narrow box section, NO NO NO i tell you!

Simply not good enough Adam is it!

So after scratching my greying hair! i cam up that for sure these elements "need more space! narturally i wanted all my oven space for cooking things! sadly i had to give up some of the much needed space to allow the elements plenty of breathing space, space where its no where near any other metals!

So i decided to make a new Base! and ineserted the elements in the middle if the sheet metal¬

I then raised the sheet metal of the orginal oven base using 2 x box sections and wired into a metal clad housing and fed it from a new hole in the back!

So far its working 100% guys

If anyone else ever does this keep in mind that you will need a good bit of depth for the elements! Looking at around 10-15cm! at least

Anyway guys thanks for all you taking the time to help me out!

and took all your comments on board!

Will i make a bigger oven? yes i sure will you guys, i sure will!

Until then this old Locker will keep em buring

Till we speak again

Adios my Amigos!
