    am I certified to Sign off fuse board?

    Not for a change of an item. But the change still needs certifying. MEIC for that.

    am I certified to Sign off fuse board?

    Even replacements must meet regulations. A replacement consumer unit is notifiable, there’s no “like for like” get out clause.

    Socket/ switch heights

    The 450mm height malarkey only applies to NEW buildings. Not to renovations, not to extensions. It is a requirement of part M / disabled access . Together with socket heights there’s ramps , wheelchair access in ground floor WCs, all sorts. Just put them nearish the height of all the other...

    10/3 120ft. Black and red On 1 breaker to keep amps up. What is the max breaker for that?

    Just pointing out a general issue in your plan and hoping you take that on board. But I’ll leave you on your own now. Hopefully there will be someone else from your region who can help you. But I haven’t exactly seen a rush of suggestions! Bye now.

    TT Eathing system to be installed

    Complicated, probably not. Cost, impossible to calculate remotely. You need a registered electrician who is experienced in TT systems. NOTE that changing from the current supply type to TT will have implications on the installations in the 6 flats and common area. We’re recent EICRs...

    10/3 120ft. Black and red On 1 breaker to keep amps up. What is the max breaker for that?

    If you double the current on one side of the circuit you MUST double the other side as well. If you don’t increase the neutral then it will melt when the increased (double) load goes through it. Not sure why you need to increase your cable size. Is it a bigger load, or is it to reduce volt...

    10/3 120ft. Black and red On 1 breaker to keep amps up. What is the max breaker for that?

    Ok, but don’t forget that if you double the conductors to the breaker (to allow for larger current?) Then you have to double the conductors on the neutral as well. The current on the neutral will be the same as on the live.

    UK How to ascertain amperage from cable thickness?

    Again, it isn’t easy. Take the example of a supply cable that has an earthed outer and two internal conductors (L&N). Typically used on TN-S supplies. The outer of the cable may be further wrapped perhaps with fabric, perhaps with all sorts of other covering (plastic, pitch, all sorts). The...

    UK How to ascertain amperage from cable thickness?

    Cable size may not be the only consideration, other loads on the phase may limit the max current available. Also, if you have a linked supply you will not be permitted to add more large load (eg EV charging) without the supply cabling being upgraded. Also there are several types of cable, some...

    Cable distance from boiler flue internal duct?

    No distances are specified, only that the installation must be environmentally suitable. So if the area is going to get HOT then you need to apply the relavent allowances when you do your cable calculations.

    weather proof consumer unit

    The meter cupboard was probably installed and supplied by the builder. Unless the back box actually is labelled something like “Board’s equipment only” then I’d go ahead and put your protection unit in the the meter cupboard. The whole of the UK is going to have to face this issue in the coming...
