How accurate is the TLC volt drop calculator
I was looking at the wiring for a shower I was possibly going to install
Not sure on the shower yet but looking at the bigger 10.5kw I went to the TLC
Calculator.
Twin and earth
Clipped to wall
Non-lighting
30 0C
1 side by side
10.5kw
230v
15metres
The result came up at 6mm (a little small I thought ?)
And just by altering the application to “above plasterboard with less than 100mm insulation” it then jumps to 16mm.
The cable will be clipped to exposed beams (old cottage) then across a small loft space (extension) to the bathroom pull switch about ½ in loft space and ½ clipped.
Is 6mm t&e about right for this cable run ????
