No, this isn't necessary. The circuit breaker protects your home by avoiding an overcharging caused by a short-circuit. It's advisable blocking the access to the breaker.

LRA is 134 AMPS. what size breaker should be used?
LRA (locked rotor amps) is not used to calculate the breaker size. Breaker's are used to protect the size of the conductor that is connected to it. Motor calculations are based on the motor's FLA (full load amps).Conductor size is 125% of the motor's FLA.Breaker size is 250% of the motor's FLA.This is the only occasion when the breaker is sized larger that the conductors maximum amperage rating. This is due to the motor drawing up to 300 to 600% of its FLA when starting.If you state the motor's wattage, voltage or amperage this calculation can be calculated here.
What must be checked when inspecting isolator enclosure?
When installing an isolator switch enclosure, make sure that the terminations are tight and secure.If you are using the isolation switch to disconnect a load that must be worked on the following should be checked. Make sure that the handle of the switch is down and locked in the off position. For isolation switches that have windows in the front of them look and make sure that the switch blades are physically in the open position. Then lock the switch in the off position. Always safety first.
What are routine tests of ac motor?
It usually depends from one vendor to another. However in general, most vendors perform below tests as routine tests: 1- No load current 2- Open circuit 3- No load speed 4- Locked rotor 5- Winding resistance etc.

You have an Amana dishwasher ADB1 Sofsound II The door is in a locked position and will not open you did trip the circuit breaker to no avail?
The handle is broken on the inside. Put your thumbs on top and pull out with them while pushing the handle up and in. With a little luck it will open for you.
How do you de-energize a circuit?
To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
Where isolators are placed in substation?
An isolator is a non load-breaking switch, and is provides a visible means of isolating a component, such as a circuit breaker, transformer, etc., from the high-voltage lines, whenever it is necessary to perform maintenance of that component. Normally, isolators come in pairs, with one on each side of the component to be isolated. Isolators are only opened afterthe load current has been broken using a circuit breaker, and must be closed before the circuit breaker is reclosed.To work on, say, a h.v. circuit breaker, the breaker must be tripped, the isolators on either side must be opened and locked off, temporary earths attached to either side of the circuit breake- to-work card, detailing the maintenance work, must be issued to the crew by the supervising engineer.
Can breakers be cut off and the breaker box locked?

With the key in the 'accessories' position it has power. When the key is moved to the start position the car loses power completely. Any suggestions?
When the key is in the "start" position all accesssories are designed to be "locked out" to concentrate all the available power to the starting circuit. How about the "on" position - do accessories have power at that position? - if not could be a bad ignition switch

Armrest in 1992 suburban in locked position?
If the armrest on a 1992 Suburban is in the locked position and will not unlock, check for a foreign object that might be stuck in the hinge. Sometimes the armrest can lock if the bolt holding it on is too tight.
What do you do with the toolbox on Game Show Island?
The toolbox (which is on the roof of the beauty parlor) is only used once or twice. It contains the screwdriver you need to: -- open the circuit breaker at the factory left of Main Street (fix the conveyer belt by restoring power at the top of the elevator) -- open the locked door at the upper right of the Nightclub (after you see a figure in the vents, go outside and use the fan to fly up to the locked door)
