The yellow P+N+E, 4h (120°) plug is a single phase connector that is in widespread use on the British Isles for 110 V building site and fairground applications. A popular model of this socket type is marketed under the brand name MK Commando [12] which leads some users to refer to all IEC 60309 sockets by the generic trademark Commando sockets.
(1) It is worth noting that the combination of a type C, E or F plug with a type D socket may often be workable; but it is unsafe to use. [37] [38] type C, E & F plugs/sockets are not accepted in the IS 1293 standard. The standard uses type D sockets for 6 A current and type M sockets for 16 A current. [39] [40] [41] [42]
Chinese dual sockets have both an unearthed socket complying with figure 5 of GB 1002-2008 (both flat pin and 4.8 mm round pin), and an earthed socket complying with figure 4 of GB 1002-2008. Both Thai and Chinese dual sockets also physically accept plugs normally fitted to 120 V appliances (e.g. 120 V rated NEMA 1-15 ungrounded plugs).
Switched-mode power supply units (PSUs) in domestic products such as personal computers often have universal inputs, meaning that they can accept power from mains supplies throughout the world, although a manual voltage range switch may be required. Switch-mode power supplies can tolerate a wide range of power frequencies and voltages.
High-voltage switchgear A section of a large switchgear panel. Tram switchgear This circuit breaker uses both SF 6 and air as insulation.. In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.
A reed switch has very low resistance when closed, typically as low as 0.05 ohms, whereas the Hall effect sensors can be in the hundreds of ohms. A reed switch requires only two wires whereas most solid-state devices require three wires. A reed switch can be said to require zero power to operate it.
