will my lighting curcuit disconnect in 0.4sec

Thanks again all for your comments.

(for Sheds) Light is an IP44 external PIR bulkhead light and will be fitted to the outside front wall.

I have noticed the trip speed in action, when a kitchen light bulb 'gave-up', and it was instant easily less than a 1 second but I'll still get it checked to be sure.

Does anybody have a ball park figure how much this type of test will cost (I live in London, is that makes a difference)

Thanks

Is it metal bodied with an earth connection class 1 or is it double insulated (normally plastic) - class 2?
I would still install the wiring to the spec required of a class 1 even if it is class 2 as unless the installation is supervised, the luminaire could be replaced with a class 1 luminaire in the future.

I have yet to buy the light, but it is all plastic construction. The instruction guide does not detail whether it is Class I or II. It is on the screwfix.com website and here is the link if you want to look:http://www.screwfix.com/app/sfd/cat/pro.jsp;jsessionid=5WD2Q4SASRAY3CJO2C1CJ0Q?id=16718&ts=99914#

Thanks again

Took another look, it does detail the light has an earth terminal therefore it is a class I
