Replacing a inside panel (60 amp) with a larger (125 amp)

Replacing a inside panel (60 amp) with a larger (125 amp) though I do not need the amps I wanted more circuits.In looking at the old panel (1960's) I find the main feed from the disconnect outside does not have a ground with the #6 coming into the panel, but has a separate wire for ground that enters the panel in a hole in the back, goes along the bottom and is twisted around a nail that drops into a hole in the bottom of the panel box.Each of the 4 circuits coming into the panel box has a ground wire that is twisted around a nail on the outside of the box which is also twisted around the ground wire mentioned above nailed into the wall stud outside the panel box. The ground wires are also then connected to the cable holder in which the main #6 wire enters the panel.This box is on the 2nd floor of a apartment.1. The ground wire was busted during remodel work. It enters as a single wire into the space where the panel box is and is tied in as described above.Where would this ground wire most likely come from. For instance without tearing all the walls out to follow it, is it possible it is heading to a pipe for grounding. Each apartment in this bldg. has its own panel feeding from the outside main panel at the meter.2. When I replace the inside panel it does not seem right to repeat the grounding as sit is presently. How should it be grounded, assuming I find where the ground wire is coming from.

Lights flicker in livingroom and will eventually go off for

Lights flicker in livingroom and will eventually go off for a few minutes ( part of kitchen is attached to same circuit) , but then will come back on. Checked breaker when this happens and not tripped. When this first started breaker would trip, so I reset it ( the breaker for all this is a 15amp), Now this problem, is the breaker to small for modern appliances, or maybe to old. House was built in 1970 and I don't think anything has ever been changed in home. I'm a first time buyer and would appreciate any info that might help. I'm a little bit of a tomboy and like to try doing things myself Nervous Home OwnerJA: What's the brand and model number of your appliance? How old is it?Customer: 1- Panasonic 1000w microwaveJA: What are all the symptoms of the problem (error codes, flashing lights, etc.)?Customer: Several things go off light w/ceiling fan, 60" HD TV, Stereo, And microwave ovenJA: What happened just before this problem started? What troubleshooting have you tried?Customer: Just unplugging thingsJA: Anything else you want the electrician to know before I connect you?Customer: No, except please help

I want to use this switch: To wire an off-grid application.

I want to use this switch:https://www.amazon.com/Leviton-1288-30-Amp-120-Volt-Double-Pole/dp/B003AUPTP8/ref=cm_cr_arp_d_product_top?ie=UTF8To wire an off-grid application. There will be two sources of 120 A/C power, one from a battery bank inverter and a second from a generator.I want to manually switch between the inverter and generator as needed. The output A/C line will be going into a single 20 AMP circuit.So essentially, I want to wire a DPDT with two A/C input sources to one output.Thank you.
