[QUOTE="Doc Hudson, post: 492842, member: 1607"] That would have been my preference as well. MR16 push connection pins are a pain in the rear. Unless there is a specific requirement for 12v fittings, (e.g. bathroom zones), I cannot see why anyone would (a) keep extra links in a circuit that can introduce additional faults, or (b) have multiple lamps off a single driver, so a single failure wipes out several lights. Not to mention if you are still using Type 1 MCBs, your board is probably quite dated, (does this amended circuit include RCD protection?), so an upgrade to a more comprehensive RCBO supply arrangement would also be a distinct advantage on reliability, functionality, and compliance with current regs. If you are changing to a different Type or Current rating, you will need to verify that the Earth Loop Impedance (Zs) is still within acceptable limits. Doc H. [/QUOTE]
