understand what the fuck he's talking about.
I'll start with one that is a "hot" issue.
48V, 0.5A is not the same as 28V, 1A and will blow up the capacitors in radios
Mind you, this is more absurd given that the AC adapters coming with these devices are 48V, 0.5A and we are swapping out for 24V, 1A...but ONLY when I'm around and he'll grab 24V, 500mA... Also, half of the jobs he does involving upgrading radios (which use more power) FAIL because of insufficient power and I have to somehow work more power or turn down power (which negates the point of upgrading equipment)
