Protest ES Ltd have 20 years of experience installing distribution boards nationwide across a variety of sectors. We offer two main types of distribution boards:

‍Three Phase Distribution Boards – 400V

Three phase switchboards are generally used and installed in industrial or harsh environments where the electrical load is much larger and can be balanced to 3 phases.


With three-phase switchboards it is possible to distribute the power to other three-phase and single-phase sub-switchboards according to the load and needs. You may also have separate measurement options, e.g. B. other buildings or lighting.


Three-phase switchboards are usually installed in industrial or commercial buildings such as, hospitals, office buildings, schools and universities. In addition to switchboards and amplifiers, heavy cabling both above and below ground is often required. MCCB circuit breakers for three-phase high power systems.

‍Single Phase Distribution Boards – 230V

Single-phase distributors are used in Industrial environments or where the electrical load is slightly lighter. For example they may be used in lighting, heating or sockets for common household appliances.


Single-phase boards are often installed in residential buildings, unless the building is particularly large, as it may require a higher load and require the use of a 400V three-phase distribution system.

If you are looking to relocate or re-wire existing distribution board installations or need expert advice on a new installation, get in touch.
