bus bar in junction bar
 
Have a 1950s house that someone rewired and connected neutral and grounds together on the same bus bar in a junction box. my question is what is the best way to fix this?? I know that this is completely wrong. it negates the point of grounding by making ground a conductor. just not sure if putting in a new bus bar for neutral or wiring all neutrals together is a good fix

need more info. is this a junction box, as you stated, or a main service panel, or a sub pane? only in a main panel which has the first disconnect are grounds and neutral allowed to be connected together. all other boxes require neutrals and ground to be separated.

is the wiring old two wire romex? on hot, one neutral and no ground. if so that is a bootleg ground and BAD. If it is, you have several options. before anyone goes over the options, clarify my first post.

Who ever did this in 1980 used and old kitchen fuse panel as a junction box. They also updated the load center butwired in this stupid junction box.

any chance of a picture of the old fuse box and the sep (service entrance panel).

reason for all this is that the new panel that was put in 1980 was a fpe. replacing the fpe and need to straighten up this mess. :furious:

The proper way to fix this problem is to shut off all the power to your house and splice the correct neutrals together. Each neutral has to be spliced to a specific neutral(s) or you run the risk of overloading the wire and creating a fire hazard. The grounds shown can stay on the bar.

I HIGHLY suggest you call a licensed and insured electrician for this repair. If things are not done properly, you can create a fire hazard or fry anything electronic you may have in your home.

i have some knowledge of electrical systems and my wifes uncle is a maintence supervisor for a large industrial company. hell be helping me just want to explore any other thoughts from any one else.

yes it is two wire romex. need the panel fixed first then this horrible junction box. then I will be ripping out all old romex an replace with 12 - 2through out house. lots of wire and drywall but its the only safe way to make it right and safe.

That is what I assumed would be the correct way. use as a large junction box until the desire each circuit properly. just exploring all options.

k_buz 03-23-2013 07:28 PM

There really are no other options that I can see.

The neutrals can not be ganged together like that except at the main or sub panel. Ganging the neutrals like that combines all the currents from the different circuits and could easily overload the neutral going to the panel. What size neutral is from the bar to the panel?

bizarre330 03-23-2013 08:40 PM

12 gauge.

joed 03-23-2013 10:11 PM

You have a fire waiting to happen. Imagine 5 circuits on one leg of the panel each drawing 12 amps. That would not trip any breakers but that 12 gauge neutral could be carrying 60 amps.
