Temporary switchboard trivia
Safety electrical equipment Temporary switchboard FAQ
By a use to use, I can greatly classify it in three on the site
■I receive a main line from chief editor board ..., kyubikuru and am used to protect the main line
■I am used in a ministry of power board ..., three 3 flight as power supplies such as motor pump air-conditioners
■I am used in a light board ..., single phase 3 line as power supplies such as lighting, an outlet, the tool
■Iron
Merit ..., the durability is high and can use it in maintenance such as the painting repeatedly.
It is heavier than demerit ..., plastic and FRP.
■Product made in plastic
It is convenient for transference slightly on-site than merit ..., iron and FRP. The price is low, too.
Demerit ..., the durability is low, and it is easy to be damaged, and repair is difficult.
■Product made in FRP
The durability is higher than merit ..., plastic and is lighter than iron. The halotolerance is high, too.
It is more expensive than demerit ..., plastic and iron, and repair when I was damaged is difficult.
As the Temporary switchboard is often installed outdoors, I often use the box which drains water off it, and was waterproofed with the roof.
The painting color often uses the dangerous color of the use of JIS safe color common rule.
Orange painting (2.5YR6/14) Nitto Electric Works D12-60X
But there is the general contractor painting in the specified color to make identification of the on-site Temporary switchboard clear.
I say the apparatus which interrupts electricity automatically when an overcurrent flows in a circuit by electric overuse and short with a breaker.
The purpose prevents the fire from an electric wire with a thing protecting indoor wiring.
In addition, there is the thing which I added a function to interrupt electricity automatically when a short circuit occurs to.
■I protect an electric wire and a wiring appliance from breaker ..., an overcurrent for the wiring. Electric overuse (overload)
When circuit nika electric current flows, electricity is interrupted automatically by short (short circuit)
It is an apparatus to grind.
[other names]
A no fuse breaker (NFB:No-Fuse Breaker)
(MCB:Miniature Circuit Breaker)
(MCCB:Molded Case Circuit Breakers)
Circuit breaker, safe breaker
■I protect a person and a building from ground-fault interrupter ..., electric leakage accident
When a short circuit (ground) occurs for the function of the breaker for the wiring, I interrupt electricity automatically
It is the apparatus which I added a function to do to. Naturally the price is larger than a breaker for the wiring, too
It becomes.
[other names]
ELB, ELCB
■Ministry of single phase 3 line neutrality line lack protection breaker belonging to
・・When the neutral line of the ... single phase 3 line type circuit became the ministry of lack state; the load state of the circuit
Accident that to become the voltage disequilibrium, and overpotential is added to a load apparatus and to break and deteriorate a damage by a fire
I prevent this. To a breaker belonging to ministry of single phase 3 line neutrality line lack protection with a ground-fault interrupter type
There is a wiring breaker type. As a main breaker of the temporary light board a use island
Do.
I check the Temporary switchboard which has been installed based on contents decided beforehand and frequency on the site
I prevent an accident and the trouble.
The following is an example of the periodic inspection.
■Does the operation of the ground-fault interrupter not have the problem? You push the test button, and do you work?
■Is there the terminal cover of the breaker?
■Does the wiring of the terminal stand not have the slack?
■Does the connection department of the terminal stand not have the adhesion such as the garbage?
■Are there not a mustache, the thing turning too much in virginity of the wiring?
■Is there the apparatus ground?
■Is there the destination indication?
■Is there not other abnormality?
Abnormality when have a problem, contact a manager for handling.
The Temporary switchboard after the removal performs maintenance as follows in us to use it safely in the next spot.
■Box washing in water
■Box painting last joke
■Box sheet metal
■The box re-painting
■Sticker cho* (manager for dangerous seal, handling principal and vice, light or power)
■Inner plane parts cleaning
■Wiring correction
■Deterioration confirmation, exchange of a terminal stand, the outlet
■Breaker movement check (sensitivity electric current level, operating time)
■Breaker terminal cover exchange
■Of the screw close it, and repair it
■Woodcut exchange
About the Temporary switchboard which I produced in our factory, I maintain it for payment.
As the Temporary switchboard publishing in the homepage uses a basically iron box
There is the weight, but is superior in the durability.
Reference weight ... safety box
As the box material has the product made in FRP made of plastic as well as iron construction, too, in consideration of construction and transference
When you want lightweight Temporary switchboard, please order it.
For more details, it is ... → What kind of kind is in the box for the Temporary switchboard?
The aluminum stands for our original Temporary switchboard superior in the corrosion-resistant durability
I recommend it.
IV is the cable which is the most common as wiring materials in electric apparatus wiring and the board.
Using non-lead PVC, I cope with RoHS order (order to limit the use of the specific harmful object).
Service life is approximately 20 years. As sorting of the color, there is black, white, red, green, yellow, blue.
MLFC (WL1) {600V combustibleness polyflextime electric wire} is heat-resistant and is superior, and it is incombustibility
Flexibility (because an electric wire is tender, bend it, and is easy to wire it) and
I am superior in current tolerance (the most high current which I can apply on an electric wire in a standard).
There becomes very little outbreak of the smoke at the time of the combustion.
Because I use the polyolefin-based covering material, recycling is possible.
Heat-resistant temperature is high and greatly gets current tolerance.
In late years I have a strong consciousness for the environment, and the cases which are demanded to use the eco-cable for the wiring of the switchboard increase.
The price generally becomes the order of IV <Eco IV <MLFC.
A board installed in the point to receive receiving supply of the electricity by the electric power company is called a switchboard,
A switchboard comes to the point where a main line was laid from a switchboard to each place.
When is connected by the light main line; a light switchboard.
When it is laid by a power main line, it is called a power switchboard.
When a short circuit occurred on the second side when I made a chief editor breaker a ground-fault interrupter (ELB)
A chief editor breaker might fall, and it becomes the cause that I cause an extensive blackout.
I plan it to short-circuit in a divergence breaker as much as possible, and to cut it off.
To temporary power supply facilities for the construction, setting of ELB is required.
