Joule Products is an accredited CUBIC Switchboard Builder, able to build type tested switchboards  with the following specifications:

CUBIC is a fully type tested modular switchboard system, according to IEC 60439-1, capable of up 7000A with a 120kA, 1 Sec short circuit with-stand. The switchboard can be sized to meet any application, which means we can provide switchboards with full bus bar access, but can equally produce compact switchboards, should the situation arise, particularly retrofitting new switchboards into existing room with space restrictions.
