What is AC line socket?
AC power plugs and sockets connect electric equipment to the alternating current (AC) power supply in buildings and at other sites. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets.
What are round pin sockets used for?
The 5 amp small round pin socket is now primarily only used for lighting circuits. Most of us will have our standard or table lamps wired into a normal 13 amp plug, with a 3 or 5 amp fuse to protect it, and plugged into a standard 13 amp socket.
What is a plug top?
A plug top is something that covers the terminals within a plug. A plug was always connected to the load and usually had pins whereas a socket was something that provided power and had shielded connections into which the plug fitted into.
How do the electrics work in a caravan?
The Caravan A modern caravan has basically three electrical systems on board. Two of these systems are 12 volt Direct Current (DC) just like your car and the third is 240 volt Alternating Current (AC) just like your house. The first system is to provide the lights that replicate the road lights on your car.
What is 5 amp socket used for?
5 amp sockets are used on the lighting circuit, meaning they are switched on and off with the light switches in the room, rather than being used like regular plug sockets. They are designed for appliances that take less than a 5 amp current, for example floor lamps, table lamps and fans.
Can you plug in a single oven?
Any single phase (domestic) oven under 2.9kW can be fitted with a 13A plug as long as the manufacturers instructions don’t state otherwise. So if your new oven is under 2.9kW and doesn’t come with a plug, one can be fitted by a person competent to do so (not necessarily an electrician) and it can then be plugged in.
What is a fused plug?
A plug fuse is a safety device which is connected into an electrical circuit to prevent excessive current flow during fault conditions. Upon overload, the wire fuse element heats up and melts, or blows with a resounding bang, interrupting and cutting off the current flow.
What kind of contact does a power plug have?
Plugs usually have a live or hot contact, a neutral contact, and an optional earth or ground contact. Many plugs make no distinction between the live and neutral contacts, and in some cases they have two live contacts. The contacts may be brass, tin or nickel plated.
What do power plugs and sockets look like?
The contacts may be brass, tin or nickel plated. Power sockets are female electrical connectors that have slots or holes which accept the pins or blades of power plugs inserted into them and deliver electricity to the plugs. Sockets are usually designed to reject any plug which is not built to the same electrical standard.
What are the standard voltages for AC sockets?
The device itself is designed to adapt to a wide range of voltage and frequency standards. There are two basic standards for voltage and frequency in the world. One is the North American standard of 110-120 volts at 60 Hz, which uses plugs A and B, and the other is the European standard of 220-240 volts at 50 Hz, which uses plugs C through M.
What are the different types of power plugs?
Plugs usually have a live or hot contact, a neutral contact, and an optional earth or ground contact. Many plugs make no distinction between the live and neutral contacts, and in some cases they have two live contacts.
