The air conditioning unit I describe here (with pics): http://www.geekzone.co.nz/forums.asp?forumid=141&topicid=138853

...has a 240v power cable wired directly into a wall plate with a single switch.

There are also a couple of fuses and relays for the unit in my switch box.

Just wondering if it is nessecary that it is wired into the wall directly (like some ovens) or if I could replace the wall plate with a standard power outlet and add a plug to the cable so that I can put a basic 240v plug in timer in between?
