Agree with you there.If a customer comes to me asking for a rewire, and the rest of the installation is as much of a mismatched mess as the intake appears to be then I'd not argue.

Guys be gentle he's still in training and has much to learn positive comments will be much better. I agree the head must be verified if it is a true three phase. Also in agreement a total load must be calculated.
I would use galvanized steel trunking and feed to either to 3 phase consumer unit or use a ryefield board to balance load and distribute if more than one consumer unit is required. But as advised by others we need a load idea to advise further.
that is a good point but the fact he has signed up to forum is positive and he has to learn as in some point in life he will need to be independent, so I would encourage him to think alone but ask his boss or mentor before carrying out any workIf he's still in training why isn't he asking his boss or mentor?

Thanks Sajeel. Don't worry, I can take it on the chin. Its quite amusing really, I have seen this on many threads on here, you ask a question and the more experienced people spend more time criticising and trying to put people down that actually answering the question. I would expect it puts a lot of people off asking a question because you have to trawl through all the negativity to actually get to the odd reply that gives a constructive answer. Its a shame really, it almost defeats the object of having a forum for discussion.
I am a project manager in fire systems and very experienced in my field. Also having been a control systems engineer for many years I am very experienced in process industries. I am now self teaching electrical books etc and will have the odd question but it appears this forum is not the place for asking. If someone asked be a question relating to BS5839 a fire installation or a control systems related question I would gladly answer, not criticise or run them down or aggressively point out all the information they had not provided in the question. Perhaps ask them to expand on the question and point them at the information which was required.
In response to above, it will be a general domestic load, not warranting any more than a 100A supply so 3 phases would not be required. Yes it is a mess hence the rewire. Someone above (I assume experienced) stated it has PVC sheathed cables why rewire, my car has tyres but they need replacing from time to time, how do you know the condition of the cables from looking at the photo. Some other comment was why rewire, because the customer has requested a rewire. Another comment was to carry out an EICR, why? It is being rewired, would you get your car serviced before scrapping it to buy a new one? See on reflection, some of the hasty comments provided above have not been given much thought and have been about as constructive as cementing bricks with margarine.

Blimey, its like chatting on a forum of barristers. May I strike my question and re-phrase said statement as "I have discussed carrying out the rewire as requested by them"From YOUR opening post
"I am currently in training but this is a family friend and I have discussed carrying out a rewire for them once I get my papers."
Discussed is very different to going to be done.
You can't always determine the state of an installation by looking at the fuse board(s) - and whilst I agree that the photo you posted may show a mess it may not actually need a rewire!
Just saying.

Davesparks I don't know why your cage is rattled there is nothing wrong with my comment based on the fact a 3 phase solution is required but a load calc will show that as stated in my post so I suggest before opening your mouth THINK
For future reference for me Dave, my question would have been relevant I guess if a 3 phase meter had been installed and all phases made available to the consumer? Then, would I need to consider load balancing. If for instance this was still only a domestic supply loading approx 100A would you be expected by the DNO to utilise all 3 phases and split the loads evenly amongst them?
Very true unless extension, basements and lofts have been added with electric showers or electric hob and ovens then load can exceed 100a easily I had one property that was tripping due to overload when I explained he required three phase head he was like I don't wanna spend that kind of money. I just won't switch on that many appliance s. I told him I will wait to hear from should you wish to upgrade as one phase has reached its load limit.
Yes I did go found issue to be extra electric shower added to extension they already had one electric shower. All appliances were fine and tested.What was tripping?
Did you carry out a load study to ascertain exactly what was going on, or how did you assess the magnitude and cause of the overload?
Yes I did go found issue to be extra electric shower added to extension they already had one electric shower. All appliances were fine and tested.
