What is an MCCB panel?

An MCCB (Moulded Case Circuit Breaker) panel is a type of electrical distribution board used in commercial and industrial settings. MCCBs provide overcurrent and short-circuit protection for higher current applications than standard MCBs.

When does an MCCB panel need upgrading?

Signs include frequent tripping, visible damage, overheating, inability to meet increased load demands, or panels that are over 20 years old and no longer compliant with current standards.

How long does an MCCB panel upgrade take?

Depending on the size and complexity, most upgrades are completed within 1–3 days. We will provide a clear timeline before work begins.

Do you provide certification after the upgrade?

Yes, we issue full Electrical Installation Certificates (EIC) and all relevant documentation compliant with BS 7671 on completion.
