If a cable was run inside a conduit which was run inside thermal insulation ( so as to completely encapsulate ) the conduit and thus the cable it would not be possible for the cable to dissipate heat ? So is the 32A rating for Method A wrong ?

Hi Looking at Table 4D5 Method A ( cable in conduit in an insulated wall ) a 6 sq.mm cable is derated to 32A. Where would this method be applicable ?

Cheers Scarypants - much appreciated !

Scarypants The cable runs pretty much trough out the run touching the side of the insulation. The cable run is approx. 15m.

Hi In my house we have the PVC Twin + Earth 6 sq.mm cable clipped to the side of a timber ceiling joist which is 200mm deep. The cable is in the centre of the joist. The same cable after crossing the ceiling drops down in a stud partition which is 150mm deep. It is not clipped to the...

Rebuke The consumer unit is fitted close to the ceiling. The cable comes out of the CU up into the ceiling where it is clipped 1/2 way down the 200mm deep ceiling joists. It thus runs through the ceiling space between the ground floor and the upper floor. It then drops down the 150mm...

Rebuke The cable is clipped directly to the timber joints. The mineral wool insulation was then fitted right up against the cable. The cable does not lie on top of the plasterboard. When you say inner wall surface do you mean the rear of the plasterboard ?

Rebuke Cheers - am I correct to say that the cable can handle 35A ?

Hi The insulation is to the side. One of the sides ( flat face ) of the cable is directly clipped to the timber frame. The strange this is that the hob has a total theoretical loading of 10.8kW, which assuming 230V is a current rating of 47A, but it only draws 34A ?

Hi I was wondering if someone could check my understanding of the current capacity of a PVC insulated Twin + Earth 6 sq.mm cable which we have installed. The cable has been clipped direct to the timber frame and has mineral wool insulation placed to the side of it. It is not grouped...

Thanks to everyone - much appreciated. :D

Cheers Shytalkz The ground material lying around the construction is typical of what I dug out. Stones and a course sandy material - no top soil and no vegetation. I was paranoid that I did not go deep enough all the way don to virgin formation ? This area had laid undisturbed for...

Morning Noseall I see you are on line. Was wondering if you could give me your comments on my previous post "Foundation for Boundary Post". Many thanks.

Hi Shytalkz I uploaded a picture of my balcony footing. You kindly helped me on this before. I would be interested to hearing if your advice changes now that there is a photo of what we did. The post is called "Foundation for Balcony Leg" Cheers - much appreciated.

Hi Many thanks. I've been looking at a lot of new houses where the integral movement bead has been used on them all externally in the roughcast ? The older houses have the stop beads filled with mastic. Cheers

Please see attached screen captures from Expamet web site.

Hi I have uploaded a picture of the footing. The concrete blocks have been used to come up to what will be the finished ground level. Any other comments ?
