Trunking for cable

[Bear2016]

I have a job of running a new cable to a DBB. The 16A MCB is in place and the oven is rated at 3.9kw so needs to hard wired. The customer has tiled walls and will not allow me to remove them to run the cable. He wants the oven switch surface mounted.
I have approx 0.5m of cable from DBB to the surface mounted switch which will be for the oven

The switch is a fair distance from the oven but what would you guy recommend using as trunking for a surface mounted cable?

Thanks

I would use trunking as trunking and I would use cable for my cable runs.......not sure I really understand this thread......Is it a wind up?

If you see the OP's only other post apart from this thread, he has introduced himself as a do-it-all renovator having recently completed the usual Electrical Trainee glut of mostly worthless bits of paper.
Two days ago he was asking for experience as he has none, yet today he is competent enough to be working unsupervised apparently.

Random question time, what is the construction of the wall?

Well one I have it in the van but secondly this is a second hand small oven for these guys and they are looking to upgrade to a bigger one later in the year when they can afford it. The trunking is temp until they re-tile the kitchen when it will be mounted in the wall. Now if the 6mm is 34A rated I can swap it over when the time comes onto a 32A MCB if need be. Just seem to make sense to me but hey what would I know I'm just a newbie at this to you oh wise great ones who proceed to flame every post that seems to be made :hurray:

What kind of oven do they have at the moment?

What kind of oven are they planning to install? How many ovens have you come across that have more than a 2.5kW element in the main oven or for the grill?
If the new oven is going to be part of kitchen remodelling and retiling etc then you'll likely be running a new supply in at that time anyway, unless you manage to follow the exact route that the chasing will take with this trunking install. And with a total distance of 0.5m from CU to switch and ~2m from switch to oven (from your OP) is it really that big a problem to run a new supply when the time comes?

Asking questions like what kind of trunking should I use is guaranteed to get a negative response as you would normally expect anyone who has gone through an apprenticeship or even the most basic training to know what trunking is available.

I think you'll find it said I had done various bits but looking for more experience. Try to read a post and then get facts right before becoming a keyboard warrior!

I have NVQ5 in Mechanical Engineering a Masters in Engineering and an IEng so not too daft and have managed multi million dollar projects for offshore. But I wanted a career change and I have been renovating properties for the past 20 odd years whilst working offshore.
I have done various electrical stuff like wire in a DBB (under supervision) and the general stuff around my home and then had it checked by a Competent Person. I have worked with 3Phase equipment wiring in motors and existing electricians in the field but domestic is a lot different and I want to get it right and ensure others are safe
I did the "worthless" bits of paper so I can grow my business and once I feel I have enough experience to join a competent person scheme.
I know after doing a 4 year apprenticeship what you learn doing that is a lot different to "out there" doing hence why I was asking for further experience. For some reason you deem that as a negative thing?
I'm sorry I am not an all singing and dancing sparky such as your good self. I just hope one day if I can offer advice on the subject I would rather than try to belittle them through a keyboard

I know what trunking is available but what have people used and why? Thats all the question ever was - I seriously wish I had left it alone and joined another forum lol

However no need to worry they have had the job professionally done for £50 by a handyman who has wired it to a plug and then into an extension lead into the ring main and said I was talking poo saying it needed to be run back to DBB.......

What's a DBB?

How are we to know what previous experience you have? All we know is that 99% of the people who do those courses come out of it a danger to themselves and other people and so we do take a negative approach to the whole subject.

DBB Domestic Distribution Board The old guy who supervised me brainwashed me with that every time I said Consumer Unit he would say for F**ks sake its DBB. Personally never heard anyone else call it but it stuck.

I agree 100% I'm amazed how some passed and there is very little practical in wiring. Most of it is testing but you do the basic CU (see remembering!) and sockets but not much at all. I understand where you guys are coming from I have been given engineers offshore who have degrees and cant use a damn spanner! They'll work out the coefficient of linear expansion for you but when oil is peeing out its not much help!

Did the old guy do a 5week course as well?

Guys please keep it on track, either help the op or move on to a thread where you can help.

How on earth do you get DBB from domestic distribution board? Surely that would be DDB?
Either way a DB and a CU are different things, and it's getting that kind of terminology wrong that instantly marks someone down as not knowing what they are talking about.

and here am i, thinking it was called a fuse board or FB, all these years. has it now changed because facebook has commandeered FB? :wub:

I would only call it a fuseboard if it contained fuses!!!

some of the ones i've come across lately have farmer fuses. horses are limping round as their shoes have fallen off due to lack of nails.
