Re: Need help - fuses / power issue
|
The theory and practice often miss. And most of the theory / rules are more legal issues then technical issues.
The "what if..." legal speculations prevail? instead of real technical reasoning.
Let's assume that the rig is using full power , say 20 A for FULL hour.
Unrealistic , but close to "prolonged" use in my book.
( you supply you own definition of "prolonged use "? )
That is 20 A !
I am not an expert on wire / gauge RECOMMENDED size, but from practical point of view
the connections? in supply and the wire will GET warm due to various real and unwanted ( fuse holder etc. ) resistance.
Now for "fire protection" - give me a realistic example of DIRECT and solid short ANYWHERE along the supply line which will blow a fuse rated to carry 20 A for prolonged period of NORMAL? use and provide "fire protection " same time .
My uneducated? guess would be 25A.
But back to the OP - the real issue was / is - the fuse holder / fuses are? NOT capable of carrying the normal usage current without introducing excessive losses? / resistance into the power supply line.
( Going from roughly? 13 V to close to 10 V is in my book excessive even without using Mr Ohm's law. )?
In other words - the fire hazard is being created and no rules are being broken.
So much for technology and legalese,
