Question about Audio Players & Recorders

1 Answer

I am replacing the original 2 prong power cord on my B&K ST 140 amp.I have installed a 3 prong IEC male connector in the back of the amp. The middle prong of the IEC connector is for ground. I plan to run a wire to chassis for ground. There is a L and a N marked on the IEC. Does it matter what wires from the amp are connected to these?

'L' is for line, or the 'hot', 'N' is for neutral. If the old cord had a polarized plug (one wide blade, one smaller), then yes it matters. The wide blade is neutral, the smaller one hot. If they are both the same, and the wires just connected directly to the primary side of the power transformer, then it does not matter.

How to wire a plug


In USA, Either the male or female plug connector would be wired the same. Black is hot wire and would connect to the BRASS colored round head screw ( Smallest flat prong or slot ). White is the neutral wire and would connect to the SILVER colored round head screw ( Largest flat prong or slot ). Green is the ground wire and would connect to the GREEN screw ( ONLY HEX shaped screw ). 1) FOR YOUR LIFE SAFETY, ALWAYS USE 3-WIIRE PLUGS WHEN REPAIRING 3-WIRE EXTENSION CORDS! 2) Check the male plug connector. It should have two flat and one rounded prong. The rounded prong is the ground wire connection. If the ground prong is missing, replace the plug. 3) Inspect the outer cover for damage. 4) Do not use cords with damaged outer covers. Taping over the damage is not an adequate repair, for safety, replace the cord.

I have a 3 prung male plug, and a 4 prung female plug. Can I switch the 3 male plug to a 4 male plug?


Hi, and yes you can, its done all of the time. You want to change the plug on the wall, not the cord. That is the way it is done. Very simple. Turn off breaker to the 4- prong. Go to any hardware store such as home depot and get the 3 prong 220 volt female plug, both are the same volts, just made for different cords is all. The male is on the cord. On the 4 prong female plug thats on the wall, just loosen all 4 screws. 2- wires are hot, either black in color, a black with a piece of white tape on it is the neutral, and a bare ground which is much smaller. When installing the 3 prong female, you will use all 4 wire to. 2- hot, ! neutral, and a screw for the small bare ground. There will be a drawing on how to connect the wires with the new plug if you are not sure. Normally, there are 3 black wires, 2 hot , 1 neutral. Some times there may be 2 blacks and 1 red. A black and red will be hot.I am sure they will all be black. The plug is marked on it. It will have L-1, L-2, N, and Ground. When you remove the 4 prong female, it will be marked the same. Be sure the power is off! L-1 and L-2 are hot, and the 3rd is N or neutral. Then the small ground. Very, very, simple to change and to know which is which. The terminals on the plug are colored also. The 2 that are copper colored are for the hot wires. The brass or silver is the neutral. And you will see the ground screw. I hope I haven't confused you, it is very easy. Just when removing the wires to the old plug on the wall, which should be a 4-prong female, the 2 wires on the right and left side of the plug are going to be the 2 hot wires. The other large black is the neutral goes to top or bottom, its marked like I said with a N. and a small bare ground. Always change the plug on the wall to fit the dryer from 3 to 4, or 4 to 3. They are both 30 amp plugs, 220 volt. Very easy, you can do this!! Please rate me on my help to you.
Sincerely,
Shastalaker7

The dryer has a four prong male plug and the outlet is a three prong female - which do I change? the dryer cord is the easiest, but how do I connect the leads?


4 PRONG PLUG WIRING: 2 HOTS(RED&BLACK) 1 NEUTRAL(WHITE) 1 GROUND(GREEN). 3 PRONG PLUG WIRING: 2 HOTS&1 NEUTRAL. YOU MUST USE 2 HOTS & 1 NEUTRAL ON A 3 WIRE PLUG. THE GROUND WIRE(GREEN) WHICH IS HOOKED TO FRAME OF THE DRYER IS NOT USED ON OLDER 3 WIRE PLUGS. IT IS AN ADDITIONAL SAFTEY GROUND ON NEWER MODEL 4 WIRE PLUGS.

Attaching Power Cable


The two outside wires of the flat power cable are the power wires. The middle wire is neutral or ground.

Hook one of the red outside wires to the red, the other to the black, and the center one to white.
