AMD 2. SPDs Shall Be Provided

whjohnson

So, again, where is the evidence that these things are actually guaranteed to 'save' your equipment? After all, if we are now required to 'sell' the concept to the customer, and then rely upon the outcome of their decision we need hard evidence that the things are actually capable of saving that "£4000 television"?

    I'm not sure there are any guarantees that apply in all possibly circumstances - a bit like seatbelts I suppose - they just weight the odds a bit more in your favour. I would have thought it self-evident that electronics and even very short pulses of high voltage aren't a good mix (as those of us who grew up playing with unbuffered CMOS ICs learned the hard way, as an extreme example), so anything that reduces the likelihood or magnitude of spikes reaching equipment sounds like a good idea to me, in principle. The cost-benefit is always a bit variable, but given the amount of electronics about these days (from the washing machine to the hob through the TV and boxes to RCBOs, never mind the EV and charge point) it wouldn't take much of a percentage increase in average lifespan to pay for a few SPDs.

    More of a challenge to me is co-ordinating the placement of SPDs - across all incoming services - including TV, phone, PV etc. so that we're not inadvertently making things worse rather than better.
