I think i am missing something..Help Please

[Wotsit]

I am instaling a night storage heater

Ib=14.78A

It=20.5A

The cable installed is a 2.5mm Flat 70' Thermoplaastic

It is installed as per method 60 Table 4A2 Which points to referance method B

Table 4D5 Does not have referance method B only A,C,100-103 Is referance method B not an accepted method of installing twin and earth?

Probably being a bit sily here
