The point I'm trying to make is that I am convinced that the limited little job I'm doing, I can do just as well as many registered electricians, because of my experience. I may not know the law by heart, but can find it and read up on it. And ask questions and get help from knowledgeable people like yourself.
You are 100% correct, and trust me, I appreciate that as well. Many can do a BETTER job than a "qualified" person (and I'm not going to expand further on that on the basis that it may start sounding VERY racist) - I don't dispute that at all. But again, just because you are driving alone on a road (with a 60Kmh speed limit), it does not give you the right to exceed the speed limit, right?
The point I'm making, is that people make mistakes - we all do. 1) You can either die from making a mistake, or 2) (even for an extremely qualified person) can spend HOURS finding a fault after it has been introduced, be it intentionally, or accidental. Again, you get mechanics, and you get mechanics. You get electricians, and you get electricians.
If you do the work yourself, and you kill someone in the process, you WILL be going to jail (that's a
fact).
The same applies to anything really. Take traffic laws. Yes, if you are alone on a road with a 60Kmh speed limit, nobody is stopping you from driving at 120Kmh. If you get caught, there are consequences. If you kill someone, there's even bigger consequences.
All I'm saying, is 1) it IS illegal what is going on here (and I'm referring to these threads in general), and 2) YOU need to be aware of it, and the risks. If you still want to break the law and you consider it to be not a big deal, the go for it - nobody can stop you (if you are really persistent), especially not I. IF something happens however, be prepared for the consequences. I'm hammering on this (due to the nature of questions asked), because it is very apparent that there are a LOT of people attempting to do work by themselves, not understanding what they do, why they do it, and why it is required. This, IMHO, is EXTREMELY dangerous.
Personally, coming back to the OP... If I was in his position, 1) I would never allow for the installation of a ripple device that I don't have control over, and 2) IF they (council / government) INSIST on installing it, I would have removed it within the first 10 minutes after they left my premises. A good quality timer device is even MORE efficient than a ripple relay, as you can heat your water precisely, when you need it...
Is it legal? More than likely not. Would they bother to check up on it? More than likely not.
