Could someone explain this comma to me? It's such a little thing, but I'm not sure what it's doing there since "an intense electromagnetic pulse disrupting, like a lightning bolt, all unshielded electric lines and electronic equipment" definitely isn't an independent clause.
I have the same confusion about a similar ellipsis question:

Until 2010, a state tax regulation known as the "80-20 rule required that condominium associations receive at least 80 percent of their gross income from their tenant-shareholders, and no more than 20 percent from other sources, like ground-floor rent for restaurants.
Sorry for being a pest and posting twice, but all the study advice says so stay persistent and follow every source of confusion until you fully understand the material. How I feel about commas right now:
How I'll feel once I've got this sorted:
Consider the following uses:
1 a. Use of "but" to join two clauses:
I can read, but I cannot write. ( comma must be included.)
1 b. Use of "but" to join two items that are not clauses (e.g. two verbs).
I can read but cannot write. ( comma must be eliminated.)
2. Use of "but" as a part of idiom "not X, BUT Y".
What I saw was not a child, but a man. ( comma is required.)
