Whilst the installation planning etc went well and the installer good I have two observations, 1) After Rob left site I noticed the CT Coil locking clip is inadequate to keep the coil closed over the power cable it is monitoring. I have fixed this using a long Tie Wrap. My understanding is this will monitor the maximum power and prevent overload, without a good secure clamp the monitoring could be ineffective and cause over heating of the house supply power cable. 2) Whilst I appreciate drilling a neat hole in the house front brickwork is not easy it would a much tidier job if brown sealant were used or better still fitting a low cost plastic burst wall cover plate that matches the colour of the brick.
