.............and mains size is? You might be better off on 3Phase/Neutral.

There are different categories in respect to multimeters and it depends on where you intend to use the meter as to what category it will need to be. Obviously to begin with, the higher the category number the higher the price. That said one can get a reasonable quality cat.4 unit with all the ranges you require for around the AUD$100.00 mark.

You'll need to provide the capacity you need first up. I take it you mean for AC mains.

Try this.............

Appears to be confusion as to "busbar" being the connection to the breakers which is correct, and neutral and earth links being the top connection brass bars shown in the load centres above.

One must remember not to dismiss the breaker itself. There are different rating such as type a, type c. Also brand can sometimes catch one out. External noise, interference, load changes can and do cause, for the most part, unexplained tripping. Fortunately for us, we have access to line analyser test gear to verify or other probably 95%. Just saying........

Isolating power first would be a given in any case. Best advice would be put the shelf somewhere else. You can be assured there will be quite a few cables behind the mortar and not necessarily in a straight plum line either.

Long time no see Aussie doctor....??? $90 for short visit these days (5-10 minutes) Get medicare refund maybe $35. Blood test at another establishment add to that. Betting you'd be forking out at least $250 to begin with. Then you need another short doctor visit fee to get results. Cheap Charlie....get insurance.

Won't be much of a megger for 1000 baht however, then all you need is someone that knows how to use it. (as per my previous answer)

Megger and a lecky who knows how to use it.

Last I looked the majority of the city was flooded to the eyeballs. Best give the locals a few weeks to recover. Can imagine the last thing on their mind would be fixing yor bruddy motorcy.

Stay clear of axial fans.........experience says they wouldn't pull the skin off a rice pudding.

Like taking ice and snow to the North pole.

Trouble with that is, things like shafts wear and seals go hard and brittle from the soap powder and before long one is back to knackered much more quickly than it prooves worth it.

Bad tradesperson always blame their tools......💥
