On protection grade and the key points of on-site judgment

Why paper is not enough

Protection grade can mislead when judged only from a datasheet, so the on-site environment is the honest referee of the claim. Dongshang New Energy shares these frontline observations from Yantai to help residents and partners judge local charging choices more clearly.

The lesson worth keeping

On-site judgment of protection grade should put standards into the process; checking against the actual environment matters more than a number on paper.

All verbal promises should become written clauses with clear responsible persons and contacts. Projects often run for years and staff turnover is unavoidable, so written records save trouble for the future.

What it means locally

Inspection frequency beats form. Rather than one grand annual check, make daily patrols a habit: record small problems on the spot and fix them within a deadline to avoid minor faults growing into major outages. Residents may combine the latest local guidance with their own driving rhythm when applying, reporting or charging daily. Dongshang New Energy keeps refining its on-site and inspection arrangements in Yantai.
