How many poles does a single pole switch have?
In relation to switches the number of poles refers to the number of switch elements that interrupt supply; a single-pole switch has only one element whereas a double-pole switch has two. A single-pole switch will function satisfactorily since it breaks the circuit. However; if a single pole switch has been incorrectly installed and is actually switching the neutral the circuit operation will appear normal but there is an active wire directly connected to the device at all times, even when the switch is OFF, which is a safety hazard. For isolation purposes using double-pole interruption of both active and neutral is much safer.
Is a functional switch a fan controller?
Yes a functional switch is all that has happened in the past.....and pretty much how it has always been via a wired fan controller with an off position, although many are now remote controlled.#N#2.3.7.1Functional Control Switching-General#N#Functional switching may be used where switching of electrical equiptment, or part of an electrical installation, is required for operational control only and not for safety reasons.
Do you have to switch all conductors in a single phase?
Yes, but they don't need to switch all live conductors in a single phase supply for the time being; but what if they fell under that Standard's umbrella? You'd have to supply an "all-pole" means of disconnection.
Do you need an all pole switch?
You don't need an all pole switch. Ignore the flyer you read it on.#N#Unfortunately AS3000 is quite clear on this subject; there is a legal obligation to comply with a manufacturer's installation instructions.
Do all pole disconnection devices need to be installed on split system A/C units?
if equipment such split-system A/C units, hot-water units, hard wired circulating pumps, permanently connected wall ovens, and similar equipment, do fall under that standard because none of them currently require an all-pole disconnection device.
Applications for Disconnect Switches
Disconnect switches are often used on generators and electrical motors. In rural situations, electricity providers often require that customers provide a generator disconnect switch if an auxiliary generator is operating on their system. This will ensure that the lineman is not in danger of electrocution.
Types of Disconnect Switches

Disconnect Switches Specifications
If you are looking for a disconnect switch to use in a specific application, there are a number of things you have to consider:
Fuse Types
Another important consideration you must make while selecting a disconnect switch is the fuse type. Fuse types will vary according to their voltage, their interrupting rating, their dimensions and their design. Disconnect switches are available in the flowing classes: Class CC, Class H, Class J, Class L, Class T and Class K.
What Are Single Pole Switches?
Single pole switches are common, simple light switches. They control one circuit and offer a regular off and on function. Most switches in a typical home tend to be single pole. Double pole switches are more common in industrial settings or factories, however they can be used as a safety shut-off for a residential appliance.
What Are Double Pole Switches?
The wires that feed electricity to double pole switches tend to be larger than the wires that feed to single pole switches, as double pole switches are often used to control 240V circuits.
Types
