LeGrand RCD Socket

Like if this guide is helpful
LeGrand RCD sockets sell fairly cheaply on eBay 9for a metal clad unit) at around £5-£20 which compares to MK at £20-£50. I found that the test/set buttons & functionalist work fine. Both the LeGrand & MK are now an inferior painted finish rather than galvanised but when a device does short, the LeGrand unit burns out internally rendering the device useless. This might have been a faulty batch on eBay. Bless eBay! :-(
