The correct way is to find a qualified electrical contractor who can examine the system, specify and install the correct, code-compliant circuit(s). Any other way is unadvisable and potentially illegal.
 
Re: Utility Control Circuit

the hour meter is directly powered by the generator 12 VDC system.
That's correct
the exercise feature is manual only based on the drawing.
That is incorrect.
The exercise feature is controlled by the timer .
they are using the 24vac transformer to power the systems control board . and to supply power to the rectifier that charges the battery

To iwire.
There is a difference between electricians and electrical technicians. Electricians install conductors. Technicians understand the way things work. Electricians don't know what buttons to push.
Technicians are button pushers. I am sure I am pushing yours. Hell none of you ever know what a rectifier is. or what about Rectification.
A simple rectifier would be a battery charger.
here is a very simple question.
What is a phase?

There in nothing in the drawing that indicates either of the above, that is why my post said "based on the drawing". I still see no reason for those controls on a system that uses a manual trasfer switch.

Well, I'm not Iwire, but I can guarantee he knows what a rectifier does.

As far as what a "phase" is, to be simplistic it is an instant in time when an element of a alternator turns through a defined (any) angle or degree from the point of zero.

What do gas fitters understand? :D

As far as pushing my buttons, knock yourself out. I am not the one who needs a hand wiring a toy generator. :D

But I am installing a 450 KW Cat, would you like to come by and see how it is done? :p

By the way, it does not have a utility sensing circuit. :p

Re: Utility Control Circuit

phase// it is the angle in degrees between the reference signal. as in sinwave.
electric generation is 3 phase of each wave being equal at all times
450 kw is still quit small.
most likely a trailer mounted completely wired at the factory. and I know you wont be the pushing the button. or in this case a switch. and if you look very closely on that prewired panel there are control boards. if your going to wire in a cat 16000KW for continuous run are you going to use a transfer switch. I guess you have not done allot of work in the islands.

there not much to this system engine, genset.some electronics. and lots of silver and copper

Yet still you are asking questions about it.

Re: Utility Control Circuit

maybe it should be asked this way.
what is the code for connecting 14awg and the 1/0 thnn the Service entrance conductors.
 
Re: Utility Control Circuit

In Art 240 Overcurrent Protection, a wire is to be protected at its ampacity. If you make a tap, the tap wire is protected by its overcurrent device.
 
Re: Utility Control Circuit

I am putting an end to this thread.

Master Gas Fitter: The rules of this Forum prohibit us from providing assistance to a person who is not an electrician and who is trying to perform electrical installation work.

You are welcome to participate in this Forum, and to learn whatever you can. But we cannot help you perform your own work.

By the way, two of your statements were wrong. First, a simple rectifier is not a battery charger, though it may be used as a component of a battery charger. Secondly, your definition of "phase" omitted the notion of comparison (i.e., the angle of one sine wave as compared to another, or as compared to a reference signal). You also incorrectly stated that a three phase system requires equality among the phases.

Take it from an electrical engineer with a masters degree who has participated in the Forum since its inception and who has observed the degree of technical knowledge and experience of its members: the electricians who participate in the Forum understand far more about electrical systems than you do.
