建议在装修开工前，专门请电工来做一次电气规划：确定所有插座位置、增加回路的需求、是否需要升级电箱，然后在装修时一并完成。" data-en="Many homeowners focus on materials and design during renovation, only realizing mid-project that 'I should have more outlets here' or 'should I add an EV charger?' At that point, any changes require opening walls or making do — all wasteful. Before starting renovation, have an electrician conduct an electrical planning session: confirm all outlet locations, identify needed new circuits, determine if the panel needs upgrading — then complete it all during the renovation.">

大多数电气改动在法律上不允许业主自行完成（除了极少数极简单的如更换相同规格的插座面板）。自己动手的风险：接线错误引发短路或火灾；接线方式不符合NEC规范；无permit无法合法完工；保险拒赔。" data-en="YouTube is full of tutorials on 'replacing outlets' and 'installing lights,' making electrical work seem simple. But in NYC, most electrical modifications cannot legally be done by homeowners (except for extremely simple tasks like replacing outlet covers). DIY risks include: wiring errors causing short circuits or fires; wiring not meeting NEC code; work cannot be legally completed without a permit; insurance claim denial.">
