Yes, if the switch is sufficient for the circuit requirements and it is installed in sight of and within 50 feet of what it disconnects.

The general rule with respect to the disconnecting means states that a grounding connection shall not be made to any grounded circuit on the -- side?
on the line side.
What is auxiliary supply?
this type of supply use in satrter, it is a supply, when we are disconnecting our main supply ,it continue oue operation for few time. that means a way is make for the supply of our operations
What is the difference between a single and a dual IGBT?
Single means there is just one. Dual means there are two IGBT's (Insulated Gate Bipolar Transistor) inside the one package.
What does it mean if a low pressure switch is checked on a residential heat pump with an ohm meter and there is no reading?
It means that the low pressure switch is open. Check the heat pump schematic to see if it is supposed to be an open or closed switch. Schematic electrical drawings are drawn in the de energized position. This means that when there is no voltage applied to the device, this will be the position of relays and contacts.
Is hydro electricity one word?
Yes, it is considered one word, hence the prefix hydro- means water . Hydroelectricity = generating water by means of electricity.
The NEC requires a disconnecting means for a service would the main breaker of the panel be code for a disconnecting means?
No, it is still live even when the switch is open...
Why you switch off circuit breakers before operate disconnecting switch at substation?
It probably doesn't matter. But a "disconnecting means", as the NEC calls it, is not intended to be operated while under load, which is when the equipment is running. It is intended to isolate the equipment so it can be serviced safely. A breaker by its very nature is intended to be operated under load. The larger the equipment, the more this matters.
What is a 3 gang 2 way switch?
3 gang means 3 individual switches in the same single unit. 2 way means each switch can be on or off.
What does a toggle switch do?
Toggle = back and forth, or on and off. A toggle switch toggles (turns) a light or other device on or off. Good example is a light switch (the wall kind)-- a toggle switch must also be of the "throw the stick back and forth" kind. Which a light switch basically is.
What is a DPST switch?
DPST is short for double pole, single throw. Double pole means that the unit contains two identical switches, side by side, and operated by one single toggle or lever. This means that two separate input wires can be controlled by a flick of one toggle. Single throw means that each switch can make or break a circuit; it can connect the input wire to the output, or not. It can't connect to one or other of two output wires, switching between them. A DPDT switch is also used for a disconnecting a 240 volt supply from a 240 volt load. Some other types of switches are Single Pole Single Throw (ordinary light switch), Single Pole Double Throw, Double Pole Double Throw, Triple Pole Single Throw and Triple Pole Double Throw
How do you de energize an electrical circit?
De energising means you are disconnecting a device from electricty source. Switch off the device, physically disconnect the device to de energise the circuit.
What is a open switch circuit?
When a switch is 'open' that means it is in the 'off' position. 'Closed' means 'on'.
When a Hawaiian woman wears a flower in her right ear does it mean she is single or married?
it means that she is single ANSWER: Correction, Hawaiian woman wears flowers all the time but when it comes to what sign it is, wearing flower on the left ear means she is single. Wearing flower in the right ear, means she is married. Thought you must know the real history behind Hawaiian sign of flowers.. Re-ANSWER: Switch sides. Right side - Single Left side - Taken/Married

What does com mean on a light switch?
In a situation where there is only one switch controlling the light or lights you normally use a spst (single pole single throw) switch that has only two connection terminals. This type of switch either connects or disconnects the two wires that are connected to the switch's terminals depending upon the position if the switch lever. The com terminal on a light switch means that it is a three way or the kind of switch used where there are two or more switches that controll the same light or lights. The three way switch is a spdt ( single pole double throw) . If you look closely you will find this designation somewhere on the switch. On the spdt switch you have three terminals, a common and two branches. In one postiion the common connects to one branch and in the second position the common connects to the other branch. If you are trying to install this switch in a situation where there is more than one switch controlling the light you must have the ability to correctly identify the common wire; if you can't do that you need help from someone who can do that correctly.

How does an electric switch help in an electric circuit?
A switch is a means of making (on) or breaking (off) an electrical circuit.
