Always been taught that the lethal dose is 50mA and anything below isn't enough to stop the heart. That must be in a Scaddan book too.
but sine! you should drop to 10/ma! or why not rely on e/f/l/z/, on .4 disconnection? YOU ONLY GAINED .2 SECS WITH RCD AT 30MA!
Again I am not debating the pros and cons but asking why a manufacturer cannot provide a piece of equipment that is safe as he must have doubts by requiring an RCD be fitted.

Another self perpetuating org ,who have nothing to loose but much to gain by introducing reems of paperwork !! ipso facto 2X hail marys and up yours
Hi, What I find amazing is that given the strict requirements of what you can have where [or what you can't!] in a bathroom you can have a shower 300mm from your nose soaking wet. Where is the logic of having this zone system when you can have a shower with no absolute requirement to have an RCD fitted? Must be pull switches but only in the correct zone [struggles to remember which one], no accessories nada nada yet you can have a push button on your shower... Yea I know its IP whatever, but still! 14th
The big mistake in the 16th edition, is omitting RCD protection on shower units - I'm very surprised that such a glaring mistake went unnoticed before BS7671:2001 was published for use!
Apparently the 17th edition will require circuits within bathrooms to be protected by an RCD. Yes, in the Draft for Public Comment (DPC) 701.411.3.3 says that RCD protection (not more than 30mA) is required for all circuits in a location containing a bath or shower.
