Metal cut-in boxes in a resedential location

[samkeary]

In my townhouse that I recently moved in to, I've had a few electrical issues that have me concerned.

1. Is it against the NEC to use metal boxes in a resedential setting with romex running from box to box?

2. I opened up a plug in my living room that was giving me issues if I plugged anything into it. When I opened it up I found wires spliced together with just electrical tape and not with wire nuts or Wago's. Is that acceptable or not up to code as far as safety and installations go?

3. The metal boxes, to my knowledge are to be bonded and grounded with the ground wire tailed out that's bonded to the raceway. If my townhouse was built when ground wire wasn't installed as a code requirement, is it acceptable to use metal boxes that are not bonded or grounded in a residential setting?

These are my three main issues that I have with my townhouse. Thanks for any help and or information you can give me with regards to these issues being cide violations that a landlord would be required to fix to bring up to code and to be made safe for me and my family.

1. No.

2. No.

3a. Raceway? You said Romex (unless you meant receptacle).
3b. New wiring is supposed to be wired per code in force at the time. Any new receptacles should be grounded. Extensions to non-grounded circuits may be made with certain constraints.

So, if I read your response correctly, the metal boxes are allowed in a resedential setting but it's not acceptable to splice wires with only electrical tape in a metal box or any box. And if the home was built to code when it was constructed, then it doesn't need to be up to the current code but to the code that was in place and being enforced during it's construction.

Are you saying that the NM cable has no ground wire? You should post a photo of what you're dealing with, as your description is confusing. Also, you should tell us when your townhouse was actually built.

If the wires are simply twisted together and taped, that is a violation.

NEC 110.14(B): Splices. Conductors shall be spliced or joined with splicing devices identified for the use or by brazing, welding, or soldering with a fusible metal or alloy. Soldered splices shall first be spliced or joined so as to be mechanically and electrically secure without solder and then be soldered. All splices and joints and the free ends of conductors shall be covered with an insulation equivalent to that of the conductors or with an insulating device identified for the purpose.​

If the house predates NM w/ ground than it would predate plastic wallcases and all of the original ones would metal.
In the early 60's some installers would just cut the ground wire off not knowing what to do with it, and some would wrap it around the clamp screw and cut off the excess maybe making it hard for you to see it.
