Load Calculation & Panel Upgrade

If your breaker trips every time you run the microwave and the kettle at once, that's not bad luck that's your panel telling you it can't keep up anymore. Construction Sewa replaces or resizes distribution boards so they can safely handle a building's actual electrical load, not the load it was designed for years ago, with proper load calculation, correctly rated breakers, and testing before power goes back on.

•        Final commissioning, labeling, and handover walking you through the new panel

Types of Electrical Panels

Fuse-based panels are the older, legacy option a blown fuse has to be physically replaced, with no automatic trip protection. They're outdated by today's standards and usually the first thing we recommend replacing.

MCB distribution boards are the standard for most homes and small commercial buildings today, tripping automatically on overload or short-circuit and resetting with a simple flip.

RCCB/ELCB protected panels add leakage protection on top of MCB protection, cutting power fast enough to prevent a serious shock. Most new installations include this as standard now.

Modular distribution panels use expandable, swappable components, so adding a circuit later doesn't mean replacing the whole board a good fit for a house planning a second floor.

Three-phase panels serve larger homes, commercial buildings, and industrial sites where the load is too high for a standard single-phase supply, and need careful load balancing across phases.

Benefits of a Panel Upgrade

•        Eliminates constant breaker trips from an overloaded panel

•        Reduces fire risk from overheating or worn-out components

•        Supports new appliances, ACs, inverter or solar backup, and always-on equipment like CCTV recorders that need a stable power supply

•        Improves overall electrical safety for the whole building

•        Allows room for future circuits without another full upgrade

•        Easier troubleshooting with clearly labeled, modern circuits

•        Improves property value, especially for older buildings

Common Problems We Solve

•        Frequent breaker trips from an undersized or overloaded panel

•        Warm or discolored panels from overheating components

•        Old fuse boxes with no automatic protection

•        Panels with no spare breaker slots for new circuits

•        Poor or missing earthing on the existing panel

•        Flickering lights or voltage drops under load

•        Corroded or damaged panel enclosures

•        Undocumented circuits with no clear labeling

Cost Factors

We won't quote a flat number without seeing your site first panel upgrades vary a lot from one building to the next. What actually affects the cost:

A site inspection lets us assess your existing setup and give you a written estimate based on what your building actually needs, not a generic package price.

Why Construction Sewa

Panel upgrades touch the entire electrical system of a building, so this isn't work to hand to just anyone. Our team focuses on accurate load calculations, correctly rated components, and installation practices that hold up to inspection from power isolation through to final testing.

Areas We Serve

We connect you with verified electrical professionals across Kathmandu, Lalitpur, Bhaktapur, Pokhara, Chitwan, Butwal, Biratnagar, Dharan, Nepalgunj, and other serviceable locations nationwide.

Frequently Asked Questions

How do I know if I need an electrical panel upgrade?

Frequent breaker trips, a warm panel, visible rust or scorch marks, or a lack of spare slots for new circuits are the clearest signs. If you're adding an AC, inverter, solar system, or an extra floor, it's worth having the panel assessed first.

Will I lose power during the upgrade?

Yes, power needs to be isolated for safety while the old panel is removed and the new one is installed and tested. We plan the work to keep this downtime as short as possible.

Is a panel upgrade the same as rewiring the whole house?

No. A panel upgrade replaces the distribution board and reconnects existing circuits to it. Full house wiring involves replacing the cabling itself, which is a separate and larger job.

What's the difference between an MCB and an RCCB?

An MCB protects against overload and short-circuit current. An RCCB detects current leakage and cuts power fast enough to prevent a serious shock. Most upgraded panels today include both.

Do you provide panel upgrades for commercial and industrial buildings?

Yes offices, hotels, shops, and factories all fall under our panel upgrade services, planned around each building's specific load and, where needed, three-phase requirements.
