    Common Issues

    Power Problems We Solve

    Expert 3-phase upgrade solutions for electrical power issues

    Insufficient Power for Heavy Machinery

    Common Causes:

    • Single-phase supply cannot handle industrial equipment
    • Factory machines require 3-phase power
    • Restaurant kitchen equipment needs higher capacity
    • Workshop tools tripping circuit breakers constantly

    Our Solution:

    We'll assess your total electrical load, apply for 3-phase power upgrade with TNB, install proper 3-phase distribution boards, and ensure your machinery operates efficiently with balanced power distribution across all three phases.

    Frequent Circuit Breaker Trips

    Common Causes:

    • Overloaded single-phase circuits
    • Multiple air conditioners on same phase
    • Heavy appliances exceeding single-phase capacity
    • Unbalanced electrical load distribution

    Our Solution:

    Our electricians will upgrade your system to 3-phase power, redistribute your electrical loads across three phases for better balance, install proper circuit breakers for each phase, and eliminate constant tripping issues.

    Voltage Drop & Power Fluctuations

    Common Causes:

    • Single-phase supply insufficient for total load
    • Long cable runs causing voltage loss
    • Multiple high-power devices competing for power
    • Undersized electrical infrastructure

    Our Solution:

    We'll upgrade to 3-phase power supply which provides stable voltage across three phases, install proper cable sizing for reduced voltage drop, balance loads effectively, and ensure consistent power delivery to all equipment.

    Cannot Install New Equipment

    Common Causes:

    • New machinery requires 3-phase power
    • Air conditioning system needs 3-phase
    • Commercial kitchen equipment specifications
    • Existing single-phase supply inadequate

    Our Solution:

    Our team will handle the complete 3-phase upgrade process including TNB application, electrical infrastructure upgrade, proper wiring and distribution board installation, and certification so you can install and operate your new equipment safely.

    Building Renovation Requires More Power

    Common Causes:

    • Expanding business operations
    • Adding more floors or units
    • Installing multiple air conditioners
    • Future-proofing electrical capacity

    Our Solution:

    We provide complete electrical assessment for renovation projects, calculate future power requirements, upgrade to appropriate 3-phase capacity (30A, 60A, or higher), and ensure your building can handle expanded electrical demands.

    Unbalanced Load Causing Issues

    Common Causes:

    • All heavy loads on one phase
    • Air conditioners not distributed properly
    • One phase overloaded while others underutilized
    • Poor electrical planning in existing 3-phase system

    Our Solution:

    For existing 3-phase systems, we'll perform load analysis, redistribute circuits across all three phases for balanced loading, install phase monitoring systems if needed, and optimize your electrical distribution for efficiency and safety.
