Maybe not the channel Spoon was thinking of but one called Technology Connections has done some features on old pinball machines.
Ladder logic can absolutely represent physical relays, that's where it started. In regards to your system, I wouldn't switch the extractor through the 8-pin relay...
The simplest reason is - that's not an RCD's job. The only job an RCD has is to compare the current in and current out through it's measurement coil. If IN=OUT then all is well. If not then trip.
There are absolutely devices who's job is to detect if current stops flowing. I've used them on...
If the connection has broken inside the appliance and contacted the chassis instead, then with no neutral return path there will be no current and the appliance will not work. The casing will be live and if someone touching it completes a path to earth/neutral they will get a shock, but the RCD...
Almost there but still not quite.
Rather than thinking of the negative half of the sine wave as 'putting voltage on the neutral', what actually happens is that voltage is still on the active wire, but now it's negative to earth reference rather than positive. The neutral stays at 0V as it's...
20 years of data experience will get you nowhere on the path to a Cert III Electrician qualification. There is one unit in third year TAFE regarding communications cabling, nothing else that I can think of will get you RPL credit based on data and AV experience, and that's assuming you have...
Don''t know if it's a universal term, but in Australia we would call the second cover inside the front door, that you can see and operate the circuit breakers through, the 'escutcheon' from the old French escuchoun.
Not obvious from the photo what brand they are, and links are very brand specific. Probably you're better off getting a full double-set from the wholesaler and replacing what's there already if using links is what you want to do.
IF the tails enter the CU through the same penetration there will be no net eddy current in the casing of the CU. You will get eddy currents in the metal wall of the single conduits, over a sufficient length this would represent a measurable loss of energy as heat. At 60A and several meters...
This mob looks like they will sell you one. How's your Deutsch?
