If the subpanel is for a EV charger or hot tub that will normally be used late in the evening, you should be OK. …

Looks like the installer did something weird here. They either installed the panel upside down and put the breaker cover on right or they reversed the breaker bus unit in the panel. You could remove t …

You're probably trying to read voltages through the paint on the panel. Try taking the reading from a metal connector screwed into a knockout on the panel and to hot. If you don't get a good reading, …

That sounds like a good plan. Is there any chance you can replace the #14 AWG with #12 AWG? You might want to add more outlets in the future and if any new outlets added in any unfinished parts would …

Based on the information you gave, no, #6 AWG THHN wouldn't be sufficient. You must have sufficient load to be calling for a 125 Amp panel and #6 is good for 75 Amps if your panel is rated for 90 degr …

So you have a 100 Amp sub panel but in it is a 50 Amp GFCI breaker so you should be OK. The only glitch would be if your new tub instructions stated that a 60 Amp breaker is needed. What size breaker …

The metal strip is a bonding strip between your neutral bus and your ground bus. You'll notice it isn't connected to your neutral bus which is correct for a sub panel but unfortunately, the grounds ar …

It's a code violation in most cases to run two wires in the same lug so a jumper from the breaker/bus hot phase to the other position on the main breaker/bus would be a no no. Connecting only one leg …

The grounds and neutrals do not have to be separated in the main panel if it is, in fact, the main panel. Sometimes there's confusion if you have a main disconnect/breaker outside by the meter. In tha …

Each sub panel needs its own breaker. It sounds like the panels are double lugged, feed enters a lug and exits to the next panel from the same lug, and that's not allowed unless specified in the panel …

If built in the 60's, grounds probably were not required on the individual circuits. I'd guess you have the two prong outlets all throughout the apartment. If you verify the metal conduit is in fact g …

I appreciate your effort to try and combine outlets and wiring but it's usually pretty hard to do. Your welder will need a 40 Amp breaker, two hots and a ground. Your future RV would probably need at …

Oh boy!! the guys will have a field day with this. Right off the bat, you're not allowed to double wire a terminal as was done in your first picture. The grounding and neutrals don't have to be separa …

You might want to think about installing a GFCI breaker in the sub panel that controls the existing GFCI outlets and then replacing the GFCI outlets with regular outlets. In my experience, the GFCI br …

Using a larger sub panel will not be a problem but the breaker must stay a 50 AMP in the main panel. You can utilize the 50 Amp breaker in the hot tub panel as a connection point for the new wire run …
