Some appliances do not have a ground wire because they are designed to use double insulation for safety. This means two layers of insulation are used to protect against electric shock, eliminating the need for a ground wire. Another reason is that certain low-power devices, like phone chargers, are considered safe without grounding. Always check the manufacturer's guidelines and ensure they carry appropriate safety certifications.
