Electrical Panel Board Installation Procedure

The method statement for installing the electrical panelboards is explained here. 

It covers scope, definitions, health and safety, supplies and equipment, installation. 

The installation involves preparing the work space, verifying supplied components, and fixing panelboards per plans, specifications, & manufacturer recommendations.

Scope

This procedure outlines the supply and installation of electrical panel boards for the work being done.

This document explains how to install electrical panels and boards:

• Preparing work.
• Material is delivered and inspected upon arrival at site.
• Install the system.

Acronyms

• PQP – Project Quality Plan
• PSP – Project Safety Plan
• QCP – Quality Control Procedure
• HSE – Health, Safety and Environment
• MS – Method Statement
• ITP – Inspection Test Plan
• QA/QC – Quality Assurance / Quality Control Engineer.
• WIR – Inspection and Test Request
• MIR – Material Verification Record.

Health & Safety

Follow the manufacturer’s Health & Safety instructions when handling and using materials. 

Ensure all personnel are aware of the guidelines.

Apply specific safety precautions as needed, as outlined in the project safety plan.

Responsibility

• Manager,
• Site Engineer, 
• Foreman, 
• Safety Engineer, 
• Technician, and 
• Store Keeper.

Materials Requirements

Components and accessories for electrical panel boards.

Equipment Requirements

The following equipment will be used for electrical panel and board installation:

1. Wire cutters
2. Crimping Tool
3. Measuring tape
4. Wood hammer
5. Drill Machine
6. Screw Drivers
7. Flat file
8. Open and box spanners

Special Control Measures

General safety, environmental, and quality control measures are required for our scope of activity; however, special control measures are not relevant.

• Proper PPE should be worn at all times.
• Permit to work at heights above 2m when appropriate.
• If applicable, obtain a lifting operation permission (using a crane) and a confined space permit.
• The approved work method statement & risk assessment shall be made available on site. 
• All personnel must be briefed on the method statement & risk assessment.

Operational Procedure

Materials

• The material chosen will be authorized by the engineer. 
• Sizes and routing shall follow approved shop drawings.

Storage & Protection

• Deliver fully identifiable component parts to site based on shop and approved CAD drawings. 
• Store above ground, sheltered from weather and building activities, as per manufacturer recommendations.

Installation Procedure

Pre-installation Procedure

• Verify all materials & documentation for this section of work to ensure they are correct and approved as per IEC 61439.
• Prior to starting construction, confirm that the sites for permanent installation are ready, accessible, and in good condition.

Installation Procedure

• All switchboards must be constructed at the manufacturer’s facility.
• Examine nearby areas before starting installation. If any condition is discovered that will prohibit the job from being completed properly, installation will not start in that area until the contractor corrects the issues.
• Repair all equipment independently of the wiring system. Use cadmium (or) nuts, zinc electroplated bolts, washers, and screws.
• Mount a single distribution board (DB) at 1800 mm from the finish floor level to the top of the equipment, unless otherwise specified on the plan or schedule.
• Ensures switchgear clearance is at least 1m or as recommended.
• Ensure connectors, cables, and component parts match manufacturer-certified drawings.
• To terminate PVC, SWA PVC, and MICS cables, secure them to switchboards using gland brackets and use glanding plates or steel extension boxes.
• For flush installation, all DB conductors must terminate behind the electrical panel board in an adjustable box. 
• For surface mounting, trunking must be installed between the board and the ceiling (or) floor level, (or) conduit must be run directly into the trunking, preventing proper installation of the trunking lid. 
• Adequate earth continuity must be established across the various components.

Post Installation Procedure

• After installation, the supervising technician for system trade should train the Engineer and Manager on how to program and operate the system properly. 
• This training will be conducted at the convenient of the staff.
• All instructions must be clearly recorded.
• The WIR shall be issued for consultant approval if the system equipment is installed according to approved shop drawings, specs, and manufacturer recommendations.

Waste Management

Rubbish generated during our scope of work shall be disposed of at a designated dumping place.

Conclusion

Installing a panel board, whether it’s a primary distribution panel (or) an electrical distribution panel (EDB), necessitates accuracy and attention to detail. 

By following the steps provided in this procedure, you can ensure that your installation is safe and efficient, meeting industry requirements. 

Remember to always prioritize safety by shutting off the power supply before starting any work & double-checking all connections before turning on the system.

What are the steps taken during installation of electrical equipment?

Equipment Installation Steps: 

1. The first step in equipment installation is planning & preparation.
2. Equipment arrival & unloading. 
3. The second step involves receiving and unloading equipment, followed by assembly, testing, installation, and commissioning.
4. Follow-up and maintenance.

Frequently Asked Questions (FAQ)

Frequent tripping of circuit breakers (CB), flickering lights, a burning odor, corrosion, or physical damage to the panel board are all indications that it should be replaced.

2). How can I find the best panel board for my needs?

The type of electrical system, total load required, number of circuits needed, & compliance with the local electrical codes all play a role in selecting the correct panel board.

3). What safety measures should be implemented during panel board installation?

To avoid mishaps while installing panel boards, cut off the primary source of power, use insulated equipment, wear protective gear, & keep the workspace dry and well-lit.

4). How often should panel boards be inspected for maintenance?

A qualified electrician should inspect panel boards at least once a year to look for signs of wear & tear, loose connections, or electrical concerns that could pose a safety risk.

5). Can I install a panel board personally, or do I need to engage a professional?

If you have electrical knowledge, you can install a panel board yourself; however, it is suggested that you engage a certified electrician to guarantee that the installation satisfies safety requirements and local legislation.
