Under BS7671 LV switchboards should be inspected at least every 5 years as they form part of the electrical system within the building housing a server room or datacentre environment. We recommend annual inspection and preventative maintenance for LV switchboards for critical facilities. LV switchboards can contain consumable parts in terms of capacitors used within Power Factor Correction (PFC) assemblies. Hot-spots can also be identified through thermal imaging and can indicate phase imbalances, potential fire and arc flash concerns. As part of an annual inspection and preventative maintenance visit all cables and terminals should be checked to ensure their torque setting markers have not been moved and that all panel meters are functional.
