[QUOTE="Sidewinder, post: 491384, member: 9512"] It's not listed in BS 7671 for the reason I gave above, there may be valid uses, but, if a device to BS 7288 does not provide additional protection then it offers no benefit over and above a normal socket outlet which is MUCH cheaper. Plus they require an upstream RCD to provide the additional protection, thus there is no selectivity. Therefore they are a device without a valid use under BS 7671, this is why they have been omitted form the listing of RCD types, and uses, and why the standard has been omitted from Appendix 1. This is down to the product standard which specifically requires they are installed with an upstream RCD to provide the additional protection required by BS 7671, and that the devices themselves do not provide this. This is going to be down to the manufacturers to sort out with BSI as the product standard that covers them has effectively rendered the products covered by the standard irrelevant. I know that at least one manufacturer is in discussions with the BSI committee regarding this. [/QUOTE]
