240 400 A is a newer item so I'm not surprised someone used a 3 phase unit. A guy I work with looked into the 400 amp setup and changed his mind when he saw the price. I used 0000 copper between my

My new GE stove the fourth wire goes to case ground N goes inside. No 120 volt outlet. A stove always used the neutral to pass current in low heat settings. R L Measures <r@...> wrote:

You can split a 400 amp run but each pair of conductors should be sized to handle 400 amp fault current. The conductor needs to match the fuse or breaker that feeds it. Your sub panel is 200 amps so

I don't know about using a 3Phase disconnect, but I don't see a problem personally. Its pretty obvious whats happening inside the disco. You wouldn't want to use 3phase panels this way. You don't have

Jim, Do you think there is any difference in the voltage capacity of fixed or variable vacuums caps by Jennings specified for the same DC voltage? 73 Peter ________________________________ From:

I have a question if I am legal by code rules. I bought this place 4 years ago and here is how it was wired. , I have my own 400 amp transformer on a utility pole in the yard, at the bottom of the

to RICH SEZ... A 15kV - tested Tune-C would do the job - provided that the DC blocker cap was ahead of the Tune-C. With a 7000V anode supply, and a g-g triode, the AC anode potential would be c. +/–

Correctomundo, Jim My GE has no outlets, but it does have a 40w, 120v lamp.

dialco makes a nice plug in neon lamp. Theis standard socket takes leds from 5 to 28 VDC (with built in resistor for each voltage) or a neon. Very nice stuff. We use them on front panels of our test

Gents My buddy was recycling his old sand filled fuses... by soldering a single strand of 26 ga wire across the 5" long fuse. Fine so far. Amp was running fine the other night... the next day... BOTH

I uploaded a small pic of a neon panel lamp assembly to the photos section to see if anyone knows who manufactures these? They are the same press in neon lamp lens that Heathkit, B&K, and several

be "safe" we need 4 wires for a 240v circuit, where 2 of the 4 wires carry zero- current? Recently when I was at Home Depot, I saw a reel of 4- conductor #8 Cu. At first it struck me as odd, but then

Jim, I'm familiar about the whisker problem, but by what I've read from several places, that happens over time and not instantly. By that, Jennings would be saying that these whiskers grow instantly

The fourth wire is in the cable to insure the safety ground does not carry current. Many 240 volt things use 120 volt functions referenced to the return placing current on the return leg. The new

The issue is not what the latest NEC requirements happen to be, it's questions like: Does it make electrical sense that to be "safe" we need 4 wires for a 240v circuit, where 2 of the 4 wires carry

Has anyone mentioned the possibility of hum that could be present with no neutral? -John, N9RF
