# Quick Answer: What’S The Difference Between SP And DP Sockets?

## What does SP and DP mean on sockets?

SP – Single Pole.

Switch isolates just the live conductor.

DP – Double Pole.

Switch isolates both the live and neutral conductor.

Use Double Pole (DP) sockets..

## What is difference between single and double pole sockets?

The pole of a switch refers to the amount of separate circuits that switch can control. Single pole switches can control just one circuit and a double pole switch can control two circuits. So a double pole switch is almost like having two single pole switches, controlled by the same switch.

## What is the difference between SP switched and DP switched?

Pole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked).

## Do I need a single or double pole socket?

In summary so long as everything is wired correctly single pole will suffice but to guard against a Live/Neutral reversal double pole switching will always ensure safe disconnection.

## What is DP electrical?

A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

## What are the 4 types of switches?

4 Types of Switches Basic types of switches are SPST, SPDT, DPST and DPDT. These are briefly discussed below.

## Do I need a double pole switch?

A 240-Volt Circuit Needs a Double-Pole Switch Circuits using only one hot wire need a neutral wire to complete the circuit, and the voltage between the hot wire and the neutral is 120 volts. … That’s why you need a double-pole switch, which is technically one that controls two circuits.

## What does 2 Pole mean in electrical?

2-pole means that the device plug is not earthed and it normally has two pins that transmit electricity. Originally, all electrical devices were fitted with 2-pole plugs, which means that the devices were not earthed and that all mains sockets were constructed for 2-pole plugs.

## Why would you use a double pole switch?

Double pole light switches, also known as a four-way switch, are two single pole switches put together. … This is typically used to control a circuit from multiple locations in a series of three switches on one circuit. A double pole switch can be used to control light and a fan or 2 lights on separate circuits.

## What’s a DP switch?

Definition of double-pole switch : an electrical switch having two blades with their contacts for simultaneous opening or closing both sides of a circuit.

## What is a 20 Amp DP Switch used for?

This 20A double pole switch is similar in appearance to a light switch, however would normally be used for a fixed appliance such as a water heater.

## Are MK sockets any good?

Mk aren’t the quality they used to be, but are still very good. I’ve fitted a few of the MK USB ones, and you can tell the quality is there with the size of the transformer and PCB.
