    Schematic Symbol
AI Thread Summary
The discussion centers on a schematic symbol in a one-line diagram for a solar-with-battery backup power supply system. Participants analyze the symbol, suggesting it represents a disconnect switch rather than a current sensor, emphasizing its critical role in safety. The symbol's ambiguity arises from a mix of American and European standards, as well as potential African influences due to the client's location in Tanzania. It is clarified that the symbol indicates a disconnect without fuse protection, akin to a knife blade switch, and highlights the importance of accurate interpretation to prevent safety hazards. Ultimately, the consensus confirms that the symbol is indeed a disconnect switch.

This is part of a one-line diagram of a solar-with-battery backup power supply system. Two inverters, one for the batteries and one for the solar panels, feed these things (one of which I've circled in red) at the inputs to a splitter, which splits the load between the two sources. I think the mystery symbol represents a current or power sensor integral to the splitter, but I'm not sure.

The drawing was made by a Canadian and therefore contains a mix of American and European symbols, but the client was in Tanzania, so it could be African as well. We use the client's country's symbols if we know them.

I think it is a disconnect box - like a switch. Agreed it is not ideal. People actually die from this type of misunderstanding - so please pay attention.
 
It is a Disconnect w/o fuse protection. Basically a knife blade switch with the appropriate Amp rating (not stated, but implied). These types of Disconnects come in the standard ratings: 20 A, 30 A, 60 A, 100 A, ... on up.

A fused Disconnect would have a diagonal line thru it and often a note for the size of fuse (which could be any value up to the rating of the disconnect),

A cross on this symbol would NOT be a disconnect but a combination motor starter.
 
Thanks. I've been able to confirm that it is a disconnect switch.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
