It doesn't matter which wire you use as hot and which one is switched when connected to a switch. I have a wiring book that has two different examples. One way white is hot to the switch and the othe
Mike, Although it's not mandatory, it a real good thing to do. When I worked as an industrial electrician, a lot of times we had to work on live circuits as the main just could not be shut off over s
However, if a neutral is in place, and it is bonded to the cabinet, in the rare event that the safety-ground is severed, the cabinet could not possibly become a shock hazard. If it is bonded to the c
The wiring manual I use states the following: A) A 120/240-volt, 30 amp receptacle (4 wires); connect the white wire to the white receptacle terminal. Connect the red and black cable wires to recepta
Perhaps 120VAC devices were more prevalent then or the tap arrangement was too complex? Recent amps designed for use with either 120VAC or 240VAC do not appear to share this issue. Anyone know what t
I still maintain the existing NEC code allowing use of a neutral is an attempt to placate some powerful special interests in the electrical industry. It is NOT the safest approach to the issue. 73, B
And, it also allows the equipment to work in foreign countries with two wire 240v -0 or three wire 240v -0 -0 service. 73/k5gw Good Point _______________________________________________ Amps mailing
Maybe the NEC is run by the same type of folks. John w4kv ________________________________ If anyone would like the address to where you can write the NEC for a code change or ammendment, I would be

As I understand it, arc-fault circuit breakers detect the RF energy from the arc and switch off the circuit. For amateur radio operators, this "improvement" should be even more interesting than GFI b
That thing tells nothing about HOW the thing works- it reads like it was written by an Ad Flack, not a technical person. If you find a real description, I would like to see it. Bill-W4BSG Bill, Indee
few days ago I ran into a Ham on 40m who is a licensed electrician here in California. so I took the opportunity to ask him why 240v appliances like ovens, dryers and water heaters need a ground wire
Without a ground/bond wire wouldn't connecting the Neutral wire to the If the Neutral was connected to the metal case it would not be a neutral, it would be a bond regardless of the color of the wire
Depends on the amplifier type and design, but the most significant factor is usually the rf device and how hard it's run. On tube amplifiers, operator adjustment is likely to dominate over everything
IMHO putting 811's in an Sb-200 is like putting a 4 cyl. engine in a Corvette. _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailma
When looking at the circuit diagram for a Clipperton L there is "an impedance matching circuit" called FI 1 - but one can not see what's in there, anyone who knows? Hello, I am not 100% certain, but
I wonder if anyone has refitted a Heathkit SB-220 with a GS-35B to replace the 3-500z tubes? I wonder how it went and any info would be of great help. Cheers John VK4AJS Vk4ajs67@optusnet.com.au I ha
To me, QSK is an absolute MUST for CW operation. Without it, you're a lid, because you can't hear what's going on while you're transmitting. Well, I guess I am a lid then, however, if you are tramsmi
Gee....guess you can include me in your list of lids, there Jim! Over 50 thousand cw contest q's and never a qsk contact among them. And you probably ought to include another 70 thousand from our gro
If a DX station is listening on or close to his frequency and has a pileup, which is the usual case in a contest, you have to be able to hear when the DX goes back to someone -- you, for example. If
