20m is the total length, 8 of which is the 4mm SWA
Yes I realise that, basically I've estimated on lowest part.
Is the supply not adequate?
Changing the T&E to 4mm will most likely allow an upgrade to 32A.
However I stress I haven't done any cable calculations.

Hi,
My initial concern was the 1.5mm cable but now the cable size has been established (thanks) it seems that I should be OK. Looking at the highest load of 2000 watts of the router combined with the 1400 dust extractor and the lighting of 100 watts…3500 seems with your estimated margin. That said, it is my intention to replace the 2.5mm cable with 4mm from the CU to the swa junction box. Have tried the table saw with the extractor and all is well.
