Title: Flexible cable size ...
Post by Lee_Elms on Jan 7^th, 2005, 9:28am

What size flex do I need for connecting some woodworking machinery requiring 16A (round pin plug / socket, 16C MCB in consumer unit) ...

(Is there a table somwhere with this information for flexible cable ? I can't find one !).

Thanks ...

According to table 4H3A in the Wiring Regs, 1.5 mm² flex will carry 16A, but if you are installing it in flexible armour, or working in hot conditions you'll need to apply correction factors to de-rate it. Best bet is to use 2.5 mm²in the first place (rated at 25A without corrections).
