LT Panel Installation, Maintenance and Upgrades

A PCC (Power Control Centre) is the main incoming panel - it receives power from the transformer or service connection and feeds the outgoing distribution. An MCC (Motor Control Centre) is a downstream panel that consolidates all motor starters (DOL, star-delta, VFD) in one location. Many factories have both: PCC as the main incomer, MCC feeding the motors. Smaller factories often combine both functions in a single panel.

We are an electrical contractor, not a panel manufacturer. We install panels supplied by the client or help coordinate procurement from a panel manufacturer as part of the project. When we help with procurement, we review the panel drawing and specification before the manufacturer builds it.

Yes - if the panel enclosure and bus bars are in good condition, we can add feeders, replace degraded MCCBs, add protection relays or restructure the internal wiring. This is usually much cheaper than a full panel replacement and is often the right call for panels less than 10-15 years old.

APFC (Automatic Power Factor Correction) panel uses a set of capacitor banks and an automatic power factor relay to maintain the load power factor above a target level (typically 0.95 or as required by MSEDCL). Factories with significant inductive loads (motors, transformers) that are paying a power factor penalty on their electricity bill should evaluate an APFC. The payback period is typically 1-3 years depending on load profile and tariff.
