The one conclusion to keep
If you remember only one thing, let it be clarifying responsibility boundaries first. Around charging anomalies this holds in most cases, and the cost of ignoring it shows up precisely when something goes wrong and no one clearly steps up to act.
Signals worth noting
Some device changes are not urgent yet deserve a note. A useful test is agreeing on response time commitments; when unsure, ask rather than assume. Most trouble we logged came from the temptation to take a shortcut around the proper steps.
Safety bottom lines
Do not modify or add parts yourself. Stop immediately on abnormal heat or smell. Delay outdoor charging in thunderstorms. Keep children and pets away from the charging area at all times, because these rules protect everyone who shares the space.
A flickering readout, a warm plug, and a tripped breaker each point to a different cause and a different owner. Naming the signal precisely in your report is what lets the right technician arrive with the right part the first time.
