there is not rcd but a dark, not blue, test button and under it ELCB trip switch is written, leading me to believe there is only an elcbLook in you're mcb board. There will be one breaker twice the size of the others, probably with a blue switch and a test button. read what is written on this. It should be the rcd.
Ok that is a good example. thanks for your patience, i am not v good with electricty etcYep its an elcb switch. I would be perfectly happy with an elcb.
Here's an example with how it would effect you.
You're cutting the grass and you slice through the cable. There is practically no chance you wont short out the cable. The blade will at some point be touching at least 2 of the 3 cut wires internal to the lead, so it has to short. If by some unbelievable chance it doesnt short and you manage to pick up the cable and touch the live wire without touching the earth wire which is 3 millimetres away from the live then there is the faintest possibility you could get a shock if you're protected by the elcb.
If you are protected by the rcd then this faint possibility is gone..
Thats the difference between the elcb and the rcd..

Simply not true.If you are protected by the rcd then this faint possibility is gone..
Think i read that RCD responds either bquicker or at a lower level of leak. Not sure cannot find nowSorry Chrisboy, but you're wrong.
The blade (assuming that it is a metal blade) can short/touch any amount of the conductors at the same time and ONLY if it shorts phase OR neutral to earth will it trip the ELCB/RCD, and it must be for at least 30mSecs (standard domestic installation) which is highly unlikely considering the speed of rotation. A short between phase and neutral will have no effect on ELCB/RCD. A full short like this is handled by the MCB or a combi unit such as an RCBO.
Simply not true.
Unless I'm missing something, there is no difference between an ELCB and an RCD. Both offer the same protection ie. Residuel current leakage to earth, nothing more, nothing less.

am i safe to use the spike with an elcb in your opinionBoth come with many differenet specifications depending on application.
