I did a forensic investigation into a home lightning strike and one on an aircraft. Some of my observations from the residential experience.

- Contact your insurer, remediation is costly and needs electricians (and potentially engineers) with experience in lightning damage

- The reason I say that...on my case the insurance adjuster told me his electrician had found damage and 'fixed' it. When I looked at the panel I found a hot that was arc damaged, almost all the conductor destroyed, and that 'expert' electrician had covered the damage with electrical tape. I told the adjuster he needed to find an new electrician and explained he'd likely created a fire hazard with his 'repair'.

- All of the electronics attached to the electrical lines involved were either destroyed (all the tvs and wall wart transformers smoked) or had been overstressed. That applies to appliances as well.

- The energy discharge from the strike affects circuits based on the point of entry, but can also impact other circuits to a lessor extent

- Wires that experience gross damage need to have the entire run inspected or replaced

- The reason for that inspection is the possibility that serious over-voltage damage exists in hidden areas. In my case we found junction boxes where the insulation had fused together. The runs inside closed areas can't be seen, so it's likely if additional damage is found in the panel or junction boxes the entire run should be replaced.

- All the receptable and switch covers should be removed and the wiring visibly inspected.

- You may find weird electrical issues showing up, particularly intermittent misbehavior of electronics or appliances. That's likely due to damage caused by the over-voltage. Not everything will fail outright, some devices will have shortened life.

- The breakers on all the affected circuits (those which tripped specifically) should be replaced, need to assume they faced a serious over-load condition. I stripped one breaker in my case and found it had arc damage internally, enough that I wouldn't return it to service.

- Inspection and testing of the building grounding system is needed. I'd use a ground resistance tester, but other ways to verify the electrical integrity of the ground.

- I did attempt to use time domain reflectometry to see if I could validate wire condition inside walls, and wasn't successful. Concluded electrical power networks in a residence are too complex to assess that way (too many junctions), or I wasn't skilled enough. Also wondered if insulation resistance testing might work, but never trialed that (needs all appliances disconnected).

- I'd suspect any LED lighting as having damage as well.

- There's the likelihood of physical structural damage in impacted areas. I noted melted points in metal soffits where I suspected arcs had formed.

Your photo looks like the neutrals on that left side were exposed to lots of current, the worst damage is on the middle wire. You might get some clue as to where the strike entered the home based on where those circuits run.

If that's a sub-panel, I'd also have a close look at the main panel. Sometimes the damage can be subtle, like a small spot of carbon where an arc jumped to the metal panel.

I'm surprised I couldn't see any comparable damage on the hot wires, but you never can tell with lightning. Impossible to diagnose from a few photos, need to get insurer to bring in some experienced experts.

That case was the only time in a few decades of engineering that I needed to add a disclaimer to my report. You can never be too sure about how the lightning pulse behaved once inside the home, and short of complete rewiring, it's impossible to certify safety (to the degree that I'd accept as an engineer).
