Ok I understand about 4 wire 240 vac service. I installed Code, 10 gauge, 4 wire line to shack and installed a end of line, inline jack. New ameritron amplifier has 3 pin plug on the end. What to do
PLEASE go back and STUDY what I and several others have written several times in this thread, and in the power and grounding tutorial that's on my website. http://audiosystemsgroup.com/publish.htm NE
Yes, and the neutral and ground must be isolated in any subpanels as well. However, there's one exception: if the subpanel is more than a certain distance from the main panel (not sure how far), such
It should be treated as a seperate building. The panel would have it's own main breaker but the neutral would remain ungrouned and the panel enclosure and equipment ground would be grounded to the se
In a typical sub panel, is the buss bar that is used to common the neutral leads insulated from the box chassis? I have installed a couple of sub panels through the years but never paid any attention
Yes, the neutral bus bar is insulated and separate from from grounding bus bar. You don't bond the neutral and safety ground from the outlet or other device together in the subpanel like you would in
Normaly it is insulated with the provision of adding a bonding screw to ground it if it is used as a service panel. If it is to be used as a subpanel with an ungrounded neutral, add a ground buss ava
The absolute safest method, using old tech 3 wire amplifiers if you have a 4 wire cord is to install a GFCI on each leg of the 220. Use it to plug in a wall wart or reading lamp, keep it balanced. If
The neutral buss bar is always insulated, but the screw connecting it to the box is flagged for removal if used as a sub panel. -- Ron KA4INM - Endless Loop: n. see Loop, Endless. Loop, Endless: n. s
If a sub panel is fed from a breaker in the main panel then it is a sub panel. A sub panel doesn't have to have a main breaker in it. Yes neutral remains ungrounded at the sub panel. YES you DO need
You need a 220 gfci. Separate gfci's for each side of a 240 line will not work. A gfci looks for a difference in current between the two wires connecting it. 73 Gary K4FMX ___________________________
The issue is NOT distance, but rather creating a separate SYSTEM. A separate system is created by a TRANSFORMER, or by feeding another building. A power system MUST have its neutral bonded to ground
All panels are built with a neutral bus that is insulated from the steel enclosure. In most, there is a large bonding screw that shorts the neutral bus to the enclosure. If the neutral bond is not pe
Read it again, Jim. In Method #1 there is NO ground conductor between buildings, and a neutral bond in both buildings.In Method #2 this IS a ground conductor between buildings but NO neutral bond in
I looked at my Federal Pioneer sub panel and I do not see a neutral to enclosure (ground) bonding screw or any where a screw has been removed. Doug _______________________________________________ Amp
Jim, Your method #1: This method was allowed several years ago but NEC no longer allows this. You must now run 4 wires to building #2 and NOT bond neutral and ground in building #2. that panel is tre
Then it is designed as a sub panel only. Lots of luck finding Federal breakers now days. Jim N7FCF -- Original Message -- From: "Doug Renwick" <ve5ra@sasktel.net> To: <amps@contesting.com> Sent: Mond
No problem finding Federal breakers here in Canada, plus I have a bunch of spares. Doug _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.c
Is this OK? I ran 3 wires (120v only) to a sub panel in building #2. I installed a ground rod at building #2 and grounded the sub panel. I will have to check to see if the neutral is connected to the
Being that it is only 120 volts you have a hot, neutral and a ground wire run out there. You should have the ground wire from the main panel connected to the ground buss in the sub panel along with t
