AC power plugs and sockets connect workshop tools and EV charging stations to grid power. Heavy-duty tools like welders and vehicle lifts require specialized sockets, like NEMA 14-50, which handle 240 volts safely. Standard household sockets will overheat under these heavy loads.
In electric vehicles, charging sockets vary by region and plug standard. The J1772 connector is the standard plug for Level 2 charging in North America. The newer NACS plug (formerly Tesla) is becoming the standard across major automakers.
Shop owners must inspect these plugs and sockets regularly. Loose socket contacts cause resistance, creating heat that can melt the plug casing. Replacing worn outlets prevents electrical fires in the shop.
