Ok, so folk are all going mad and fitting SPD consumer units et al.
BUT - How effective will they actually be?
In other words, what steps are in place to monitor and record the effectiveness of these devices?
So the flag turns from green to red over time, yet the consumer unit continues to deliver regardless, and the customer notices nothing changing, in the same way that they never test RCDs by using the test button.
How will we ever know whether or not these devices are actually worth the money? Or is it a case of another successful snake oil sale?
How long will it be before a future EICR flags up the fact that the SPD has 'died'.?
