  • Internal Inspection Report / Joint Inspection Report.
  • Quality Assurance Planes.
  • Calibration Certificates  of Test Instruments
  • Warranty Certificates on Products



Quality Control Wiring Accessories

All the  Control Wiring accessories and hardwires  are to be chosen based on Reputed Brand, ISI Marked enable , and Quality of  durability that leads to make perfect Inside of the Control Panel Circuit wiring, Because Inside of the Panel Circuit is known as a Heart of any Electrical Control Panels.  



Connecting wire is used to connect all equipment according to  the circuit diagram. There are various colour and size of wire. Depending on the current rating the size of cable is selected. 




 A terminal is the point at which a conductor from an electrical component, device or network comes to an end and provides a point of connection to external circuits. Mostly use terminals are Stud type terminal and screw type terminal.




 Sockets are devices that allow electrically operated equipment to be connected to the wire. Electrical plugs and sockets differ in voltage and current rating, shape, size and type of connectors. It may be pin type, ring type, fork type, barrel type.

Cable duct:


A tube used to protect and route electrical wiring. It may be made of metal, plastic, fiber, or fired clay. In most cases plastic, flexible conduit is used for some purposes.




A ring or cap usually of plastic put around the end of wire to detect the connection flow. Usually it is used both side of wire with a specific code. And that code denotes the connecting path of that wire.






Cable Ties are designed to secure wire bundles and harness components quickly, without slipping.The common tie-wrap, normally made of nylon, has a flexible tape section with teeth that engage with a pawl in the head to form a ratchet so that as 

the free end of the tape section is pulled the tie-wrap tightens and does not come undone.


Spiral binding:


Coil binding, also known as spiral binding. It is used to bind the wire properly. Spiral coil binding spines are also available in more colours and sizes than other binding styles.




Gum saddle:


It is used to fit the wire in the panel wall properly. Normally it is made of plastic. Wire is fixed to it tightly by tie. 




Nut bolt & washer:


Lock washers are almost always used with a flat washer as well. The nut is also often smaller in profile 

than the bolt head. Not always, but often. The washer helps distribute the pressure that the nut places on the surface of the fastened objects.

Maintain of Degree of Protection

IP Rating – Ingress Protection


The IP rating is used to specify the environmental protection of the electrical enclosure which contains the components and control equipment, often stated when panels are likely to be placed outside or when there may be contact with water, dust or other particles

Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures - IP Code), specifying the environmental protection the enclosure provides.

The IP rating normally has two (or three) numbers:

  • Protection from solid objects or materials
  • Protection from liquids (water)
  • Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 6052

Example - IP Rating

With the IP rating IP 54 - 5 describes the level of protection from solid objects and 4 describes the level of protection from liquids.

An "X" can used for one of the digits if there is only one class of protection, i.e. IPX1 which addresses protection against vertically falling drops of water e.g. condensation.

IP First number - Protection against solid objects


No special protection.

Protected against solid objects over 50 mm, e.g. accidental touch by persons hands.


Protected against solid objects over 12 mm, e.g. persons fingers.


Protected against solid objects over 2.5 mm (tools and wires).


Protected against solid objects over 1 mm (tools, wires, and small wires).


Protected against dust limited ingress (no harmful deposit).


Totally protected against dust.














IP Second number - Protection against liquids


No protection.


Protection against vertically falling drops of water e.g. condensation.


Protection against direct sprays of water up to 15o from the vertical.


Protection against water sprayed from all directions - limited ingress permitted.

Protected against low pressure jets of water from all directions - limited ingress.


Protected against temporary flooding of water, e.g. for use on ship decks - limited ingress permitted.

Protected against the effect of immersion between 15 cm and 1 m.


Protects against long periods of immersion under pressure.






Few Essential Steep for Electrical Control Panels Design.

1. Your Requirements

The starting point is for you to give us a detailed functionality spec of what you want – what the application is and its specification, and an idea of what you’re trying to control, and what you want it to achieve.

We aim to make everything as easy and efficient as possible for you, and so we also ask you whether there are any specific brands or types of components that you’d prefer us to use.

This ensures if your operators or engineers are more familiar with a particular brand of PLC or Variable Speed Drive for example, then manufacturing the control panel with those components reduces the learning curve for them, and makes maintenance and servicing much easier and much more cost effective.

2. The Offer

After we’ve received your detailed specs we issue you with a firm price for the project. This will be the final price; there will be no hidden costs and no additional extras. Once the price is agreed we then wait confirmation from you to proceed.

3. Electrical Schematic GA & SLD Panel Layout drawings

We now prepare the CAD schematic drawings for both the panel layout and the electrical circuit of the panel. Once these are complete they are sent to you, the client for full approval. Manufacturing can only commence once we have the written agreement. This ensures all parties fully understand what the final product will look like and how it will work.

4. Manufacture and Test

Next we manufacture the control panel. Das & Company have full ISO 9001 Certified and used Certified Bus bars, High  Quit Wiring as per ISI standard, Thorley Routine Test,  All our panels are manufactured and tested using these manufacturing standards

5. FAT Workshop test and functionality simulation

Once manufactured you, the client, are invited up to our manufacturing facility for a Factory Acceptance Test. The testing includes functionality testing, where we simulate the operation of the machine that the panel is being built for, and make sure that operates correctly.

We test the panel as thoroughly as we can at this point to your complete satisfaction. If you, the client, decide upon any modifications it is at this point they can be agreed and carried out.


6. Delivery, Installation and commissioning

Once that testing is completed to your complete satisfaction we deliver the control panel to your site. We can then offer full installation and commissioning services.

We then perform a series of additional functionality tests on-site to make sure that the panel operates correctly in-site.

7. Completion and sign off

Once the panel is installed, commissioned, and functioning correctly with the rest of your machine, you, the client sign the project off as completed

We then work with you through a handover period, which will include training and operator training if required.

All of our control panels are built to current standards and regulations, and come with a 12 months warranty on parts which can be extended by prior agreement. All control panels are certified to the latest ISI standard.

Working closely with the client and understanding their requirements, followed by 100% visual and electrical simulation test, ensures that the equipment which arrives on site is exactly as the client envisaged and will operate the second it is switched on.

If you are looking for a company who can interpret and understand your requirements, if you want to deal with Quality Products  and Qualified Engineer , not Chipper Product If you want to and you want a cradle to grave service for you control panel needs whatever the size and complexity of the product then Das & Company are the right choice for you.
