4-Way Metered Supply Isolator with 100A Isolator and Surge Protector - WCED WEC440SP

A nicely packaged solution offering a type 2 SPD that can be mounted where a normal isolator would be, so well within the 50cm of the origin of the installation from the regs. Nice that it also gives the option to output two sets of tails, saving on separate blocks. Had no issues fitting it. Torque specs were provided, and the switch gear was seemingly good quality, as was the plastic casing. The bus bars linking the two outputs are designed so they stay in relatively easily even with the terminals open for terminating the tails, making installation easier. Would buy again.

A neat compact surge protector which has to be fead from the top, as unlike most SPDs which have the earth at the base this enclosure is so small and tight you cannot reverse the internal wiring. my picture shows the main tails which being 25mm do not like very tight bends. However it does the job ensuring fault currents travel a minimal distance to earth well within the 50cm recommended. This unit represents exceptional value for money and is much easier to install than the metalic versions.

As a previous reviewer has stated, the entry holes in the enclosure (at the bottom) don’t line up with the isolator when using 25mm2 meter tails. This is made more difficult if the meter tails aren’t flexi-tails. Once fitted, tug test on the tails showed that the screws weren’t quite gripping the cables as well as I’d have liked. It’s a shame both sides of the isolator don’t have two screws and that this is only in the incoming side of the isolator. Nevertheless, great solution for introducing surge protection without the need for adding or replacing entire distribution boards.

Good way to upgrade to the new UK regs Surge protection device should be fitted to new installations and recommended for existing unless you can prove otherwise with risk assessment which is more of a pain than just fitting one This is fitted in the meter box next to the cut out fuse bottom right of box leaving the top half of the box for the meter The isolator is double terminal on the live side only If you cannot isolate your supply other than with the cutout fuse I'd get this fitted by your energy supplier when they fit a new meter as your not allowed to pull the cut out fuse and national grid will charge 4 times the price The spd is connected by a bus bar in the inclosure and will need 10mm to 16mm earth cable to connect it to earth dependent on the impedance of your earth Once fitted the installation should be voltage surge protected this one has a green indicator on it after a few years and operations will need replacing once red shows can be replaced without opening enclosure as its module is push clipped into its base so can be squeezed and pulled and a new one pushed in I would also put a decal in the consumer unit this feeds warning that a spd is fitted in the meter box as if a sparky insulation resistance tests the circuit he may damage the unit and or get false readings the spd needs removing before the tests

Good product, takes up very little space yes very happy and cheap

Just the job

ELECTRICIAN REVIEW: I generally avoid installing anything in meter cupboards, however if you are replacing a 60947-3 iso fitted by the DNO, these are absolutely perfect!!!

Great product but how do u reset once tripped? I'm assuming u just turn the switch off and on again. Unfortunately no instructions
