As I've noted in another thread. The electrons don't care what colour the insulation is. Electricians do, but then check the function anyway. Relying on wire colour (particularly in Thailand) is unwise to say the least.

Cripes! We are usually awakened at sparrow-fart by the wat next door getting the monks out of bed. And Madam's creatures wanting to be let out and fed (except the fish, they are very quiet)

That's great, if the one with no wire is turned ON then it will light the neon, no issue. Now check at the bedroom light switch, with the light ON both wires should light the neon.

This ^^^ I understand 100%. Long, long ago when I was at uni. I would go home each weekend; it was only an hour on the bike (Suzuki GT250 - did I say it was a while back). After a few months it became, every other week, then once a month, then mum would call and ask if I was coming home this year!

It may well be, but it's also a good opportunity for her to bond with her course-mates and be a good grounding in "independent" living. Is the cost really that prohibitive?

It's at times like that that good diagnostic technique is important. He measured at the meter and found 2A going "somewhere". If he had then measured at the point the overhead went underground, he would have seen no current. At this point he would know that the "leak" was between the meter and the underground section. It's called the "half-split method" and is one of the earliest fault-finding techniques taught.

If it was on the house side of the meter it's your problem despite being on the PEA pole. I'd just be happy it's sorted.

So when did they bury the "reputation" or likes count?

These kinds of "improvements" are outside our control as they are implemented by the software vendor. We have to take the updates if we want to keep support -
Are you suggesting that the switch should be in the neutral?????????

I believe it won a competition in Wireless World in the 1970's.

You can tell a REAL electronics lab by the sweet aroma of fried electronics!

We only have mains outdoor lights on the upstairs sitting area, unfortunately the one place suitable for a photo-switch can "see" the lights it controls. For ages I was using a carefully shaded sensor but in the end gave up and just put them on a timer. All our other outside lights are solar and controlled by the solar charge controllers.

Power ON, finger on the end. You can also check the screws on the small breakers, they should light the neon.

Electrons do not worry about the colour of the insulation. Electricians look at the colour, then check the function anyway!

Not at the fitting. The swap would be at the supply end.
-
Just check the most annoying ones 🙂 You should also check that your incoming supply isn't reversed. The bar on the left with all the white wires should NOT light the neon.
-
Do you have a neon-screwdriver (the type you put your finger on the end to check for live)? If so, with the switch pulled off the wall and turned ON (light lit) check if the terminals of the switch light the neon (they should). If they don't and with the switch OFF one terminal is live and the other isn't then you have a switched neutral. Switched neutral is the No.1 cause of lights glowing (or CFLs flashing) when off.

Really, I thought red was for the second 120V phase. So red and black are both hot, white/grey is neutral and green is ground.

Charging an EV with solar cells
Crossy replied to edwinchester's topic in Alternative/Renewable Energy Forum
All good stuff above. The problem with charging directly from solar is that solar isn't constant. That coupled with EV chargers being fixed rate (or at least not remotely controllable) makes life a bit difficult. By far the easiest / cheapest way to do this is to go grid-tie with an inverter that has a current-transformer so it can be set to not export to the grid (with an electronic meter you really don't want to export). A 5kW grid-tie inverter with about 6kW of panels will easily power your granny-lead during the day and any excess generated will go to offset your daytime domestic usage (which also applies whilst you're out and about in the EV). There are solutions that provide a variable charge rate EVSE (Electric Vehicle Supply Equipment) but off the shelf units are expensive and not everyone wants to start playing with something like Open-EVSE. -
Thanks for the photo. Looks fine. I was a bit worried that your man had somehow hooked up the LED unit to the existing choke/starter which could lead to "interesting" effects if it wasn't specifically designed to be that way. Now you know how to read your meter did you manage to check the supply voltage?

UK regs allow any colour for earth, so long as it's over-sleeved green/yellow at connection points. Domestic twin and earth has a bare (uninsulated) earth core, sleeving required at the ends of course. What is absolutely not permitted is the use of a green/yellow core for anything other than earth (no over-sleeve permitted). In Thailand, pretty much anything goes in domestic 😞

It's all about the money of course. The US is not the boss of Thailand no matter how much they like to think they are. Any country following US or, more likely UN, sanctions do so on an individual and purely voluntary basis.
