Morning. We have a draft City Power document dated May 2016 that states that the maximum PV generated on-site may not exceed 75% of supply CB. Is this still correct?

Where are you located?

I don't know the answer.. in fact, I don't really understand what exactly are you asking? Are you saying that the City limits your power production you are pushing into the grid?

What is "CB" ?

I'm just interested

Which City? George? PE? or WTF is it called now? Either way, if PV generated is 75% max of commercial CB supply, then let us assume you have 60A breaker from "the City" 75% of this is 45A at 230V, so (where's my fscking calculator) just over 10kW's worth of Solar panels would put you within that limit... in my case that amount of panels on a sunny day (most days are) would generate in excess of 60kWh for the day, although, since I don't have use for that much power the current 17 * 280W JA Solar panels produce 32-33kWh per day at the moment and we do use that power...

I don't think it will be as simple as - Circuit Breaker?

 

Common base (CB) configuration (or) Grounded base configuration?

What is CB in electronic?

 

 

Common Base (CB) configuration (or) Grounded base configuration. In this circuit arrangement, input is applied between the emitter and base, and output is taken from the collector and base. Here, the base of the transistor is common to both input and output circuits and hence the name common base connection.

 

No idea if this is correct - this is just what uncle Google digs up.

Uncle Google has lost his marbles recently with AI bull creeping in, the search results are getting less useful, CB is in Electricians slang a Circuit Breaker, this may well be primarily the case in South Africa, possibly also in other English speaking countries, but no guarantees on that one.

DC and transistors will not come into play when you talk about your electrical supply, since it would be AC and the 1st Circuit breaker fed from the grid determines, normally, the maximum power you can expect to draw.

Actually, if you just change the search from "What is CB in electronic?" to "What is CB in electric?" Google and it's AI answers perfectly.

Even AI is not clever enough to answer the question you had meant to ask....

This is interesting, what question do you think I meant to ask? I was answering and pointing @Demo in the right direction.... Gurgle does not always have reasonable answers and worse so recently, now they are only giving remotely reasonable answers when your browser allows Javascript to run, which should really be optional, in my eyes anyway...

I was not referring to any question you had.  My apologies if that was not clear enough for you.

The question that was asked by @Demo was "What is CB in electronic?".

The question that I assume @Demo meant to ask was "What is CB in electric?".

Assuming that you are talking about Google, I guess it all depends on how you use it.  If you are going to use "electronic" in a query when you mean "electric", I think that it is a bit harsh to blame the tool when it returns an answer based on the actual question asked.

True, but the fact remains that it is getting less useful in the results provided and I for one, will start to wean myself off this 25+ year reliance on Gurgle as the usefulness spirals the drain and the motto of "Don't be evil" has been shredded and turfed by them many times over the last umpteen years, the new motto "Do the right thing" begs the question, for whom? most likely the shareholders, I'd think...
