Yep. CRT scopes did this to generate the sweep voltage. I've been involved in a few of those designs. Relatively slow sweep speeds for NTSC waveform monitors. Although I did troubleshoot higher speed scopes for a few years.

This would have cleared up a question I had yesterday. Oh well...

Good luck.

Wood screw vs metal. Both are made for ribbed sheeting. Polycarbonate that matches the steel. Better pic of the type of ribs I am used to 9 inch on center between ribs. Each sheet covers 36 inches. Care needs to be taken when installing to get the rain groove under the adjacent sheet...

I do. Unless that sheeting is different than I think it is. I'll snap a pic on a building I have and post it.

So is that some type of form underneath the clear sheets on top of the beam that goes across? Are they a substantial form? It's possible they are there to take the stress so the screw can be run in on top of the ridge. Seriously reduces leaks. Still an issue to get a screw made for wood to go...

I'd like to see a few pix. Does it leak on every screw?

You cannot get 3 phase from single with just transformers. Scott Ts were common to go from two-phase 90° to the more commonly known 3 phase 120°.

The point is that as far as I can remember on this forum I have never gotten a straight answer as to how the electrical system in the UK was done concerning grounding. You said yourself: But, apparently not according to others and you also said: Now concerning a floating system to remain...

Both you and @sophiecentaur seem to be missing my point. Of course I realize that an RCD works by sensing unequal currents in the live and neutral. Those currents will NEVER be unequal if the system is completely floating. The system has to be referenced to something else (the earth) upstream of...

Ok. Makes sense. So line and neutral do not float.

This is the one that confuses me. If it is expected that an RCD will trip, the system must be referenced to a ground rod someplace. The grounding wire attached to the chassis of appliances is attached to the customer supplied ground rod as I understand. Well and fine but if the line and neutral...

I see. This explains the confusion and seemingly contradictory explanations I have experienced in the past.

So what happens if you connect a resistive load such as an incandescent light bulb between live and the metal chassis of some known good appliance that has all three pins? Will it trip an RCD somewhere? Will the bulb simply light normally or will it be dim due to the extra resistance of the...

This makes no sense in the context of this thread. If N and L are not referenced in any way then what is the point? Not possible. You cannot rely on the soil to blow a 20 amp fuse. Too much resistance. Unless what you mean is what I already said here:
