DC power for 12V cordless drills

摘要

I agree with your superb warning on page 8 of the October 2008 issue regarding using a 240 VAC power board for 12V DC. But there is a really simple solution. Electrical suppliers have 32V 15A fittings such as polarised plugs, line sockets, surface-mount outlets and outlets on a steel adaptor bracket which will fit into a standard weatherproof box for 240VAC switches and GPOs.
