I am wiring a 3 prong 220 plug in a feeder panel with 12/2 wire. Should I hook the ground wire to the ground bus or to the neutral bus? The neutral bus is isolated from the ground bus and the panel box.

This is off the mainline above the weather head. On the end the wire got pulled out after a tree fall. Was this a fix from a previous wire rip?
Can someone suggest how I could go about fixing this or should I just pay the electric company to fix it? Im thinking just buy a new adaptor and...
I embarrassed that don't remember this but swallowing some pride is sometime good for a person. I am wiring a 3 phase in-line water heater and the manufacturer lists the current draw at 177A. at 480 volts, (144kw). Would that be per phase rating or would that be just the total. I was thinking...
I have moved back to my house i was born in some 60+ years ago. Most of the original house's electrical receptacles are 2 prong with the center screw that holds the cover plate on as ground. They all test, OK. My parents had an addition installed on the second floor sometime around the mid to...

Hello, I’m going to be installing a wall charger soon in my garage that requires a 60amp breaker. I’m wondering if it is ok to add it to the garage sub panel (there are open spaces) or if I need to add it to the main panel. DIYer here.
The plan is to run the breaker to a disconnect switch...
Was called to a complete previously scheduled work. Prior to arrival was called to say she was having electrical problems. This client has a large 40 year old home, with an 150a pushmatic main panel. No work has been done on the home recently. This is what I witnessed:
Some circuits worked...
I have a 240V range top that needs a wall switch added (for preventing an elderly person from using it when unattended). The existing feed is one black, one red, one bare ground. Which color leg should I break with a switch? Thanks

Hey all, I bought a big garage that I’m going to subdivide and rent out. I am going to hire an electrician to do all work. This is not a DIY question. I just wanted to ask for advice here before hiring an electrician, so I know what I’m getting into. Thanks in advance.
The space is 2500 sqft...
