If I have things right twin and earth cable was never designed to go in insulated partition walls but due to changes in building design has ended up in these walls and the IEE/IET/BSI have produced a table 4D5 to assist when using this cable and we have installation method 100# to 103#.
However Ali-tube cable to BS 8436 GuardianTM, EarthshieldTM or FlexishieldTM according to manufacturer rated at 90oC rather than 70oC and is specially designed to be used in partition walls so where is the table to tell us the current limits for this cable with installation method 100# to 103#? Reference method 1 and 11 are given neither of these refer to partition walls. We are referred to Table 4E2A page 286. I wonder if the figures in Reference method A are to be used instead of 100# and 102#?
Has anyone found manufactures data on this cable giving installation method 100# to 103#?
