Service Entrance or panel

The boy put us a pole barn. Now he is installing the entrance panel. He asked me if it makes a difference if the red wire is on the right and the black on the left or the other way around. It is being fed through the shop's 200 Amp service entrance by a double 50 amp breaker.Thanks for any help. J.
 
J.S,

That may be denpendent on the year of NEC your area may have in effect. I'd think shooting from the hip tha tif you have other panels, the established color coding, in order, may require a black, then red, "hot".

Please do not hold me to the unknowns.

This is Australian 240 volt AC code of course .

The saying is '' The left hand is the hand of the Devil '' so active or red goes to the left , black or neutral to the right .
 
I know with three phase you can have a high leg but single phase 240 shouldn't make any mind. There are codes but as far as "CODE" you may want to stop by your local electrical supply house or Google it. Try electrical codes and go from there.
 

I have never wired a panel but have been into many. I always thought that it was probably an unwritten code where you are an idiot if you don't do it the way everyone else does. Our local building inspector occasionally tries to enforce rules that he makes up, but the tradesmen will tell him that they are going to stick to code.
 
JS, for 120/240 volt single phase three wire service neither side makes a difference as far as the two ungrounded conductors are concerned. HOWEVER as that's a Sub Panel fed from your other panel, unlike at the main, the Neutral Buss and Equipment Ground Busses are separate and isolated from each other, IE the Neutral Buss has no bond to the Ground Buss. The panels metal tub frame is, of course, bonded to the Ground Buss. Also a buildings electrical service requires proper grounding, it varies in jurisdictions, perhaps one or two Grounding Electrodes such as "made" electrodes being copper rods driven into mother earth along with other "readily available" Grounding Electrodes.

That only applies to power companies and what they want in the meter pan or high leg service in the panel.. In this case it does not matter.Actual " red leg " high phase is taped orange anyway not red .
