Can using an under rated power source make it pop and smoke? i.e What if I connect a power source rated at 4 Amps to some equipment that may require 6-10 Amps. Will that damage the power source??

Parts

What would be the best way to cut out any part made with Lexin or Air Craft Aluminum as a substreaight with an exotic wood vaneer bonded to it. I need it to be cut to exact tolarences so as to fit into factorey specs. The aluminum would be about 3/32 thick and the lexin would be about 3/16 to 1/8

ANSI compliant Generators

I heard to be ANSI compliant on Generators that the 3 phase fault must be greater than a SLG fault. And a simple 2500kW generator from CAT doesn't do that. So if I want to buy an ANSI compliant generator than who pays/installs the Resistor in the neutral to limit that fault current? thoughts...

Mu-metal Faraday Cage?

Ok, short of doing the experiment myself which I probably will, I wanted to know why it is not possible to make an effective Faraday cage from Mu-Metal?

It seems logical that any good conductive material like Mu-Metal would also shield at least some RF and certainly Static Electricity, but no
