    Following up on the recent thread about Earth Resistance measurements

    This particular forum is not likely the place to get your needed advice. We've covered the technical end of what is safe and what is safest. We are pretty much in agreement. Even though we are on opposite sides of the Atlantic electricity behaves the same. At this point it is whether or not you...

    Following up on the recent thread about Earth Resistance measurements

    Ok. I suspected as much. Here in the USA the transformer is seldom very far from the service panel. Several hundred feet at the most. There will be a ground rod at the transformer as well as one at the service panel for the residence. Two in a lot of cases because NEC says if the resistance is...

    So what is to stop you from joining the earth and neutral in your main panel? You would end up with TN-C-S right? I'm not suggesting you do this. It is truly a question. Post #34 touched on this a bit. I can't see how it would not be safer than leaving it as it is.

    In the USA no matter how old the service is there is nothing stopping me from updating to a 'safe' installation by adding three wire circuits or replacing the main panel, etc. Those costs are on me. There is no TT, TN-S, etc. All residences get two hots and a neutral. Very very old residences...

    @sophiecentaur based on your last post then I see this as you simply want an updated system. Why the beating around the bush? - As far as this goes: This is a straw man argument. It may be your opinion and of course you are entitled to it. If systems like this exist and are not on a list for...

    Based on the above, I don't see why the power company should be responsible for the scenario at hand. If this was an accepted practice at one time then it should be now. The ground rod may in fact be missing or previously removed, etc. Of course this is not correct and needs to be dealt with but...

    How can I find the cleanout for my building drain?

    Or you could probe thought the soil in your yard to find the pipe. This is not an uncommon way to find things that are not buried very deep. Use something with a round point.

    Electrical Unused light switch in the living room?

    It's not uncommon for a receptacle to be split. For instance the bottom may be live all the time but the top is controlled by the switch.

    Capacitor charge time, two conflicting answers

    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.

    Construction Water sealing a large corrugated roof - after-the-fact

    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.

    Construction Water sealing a large corrugated roof - after-the-fact

    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?
