Can I earth the energiser to the earthing for the mains supply or the water pipes?
No, in fact its illegal to do so. You must install a separate earthing system. Back to top of page _______________________________________ Please explain the insect resistance feature. We currently use a golden varnish with an anti-fungal ingredient built in. Before we dip the PCB we hot melt glue across the pins of the Thyristor. The reason for doing this is that the high voltage released by the thyristor attracts insects. Thus shorting out the component, which causes the PCB to fail. This has greatly reduced failure rates coming back to us.
