FAQs - Electrical Works

All our electrical contractors and electricians have to be IEEE 18th edition approved and certified by one of the national electrical contracting associations: the ECA or NICEIC. On completion of any electrical works, our qualified electrical team provide the necessary electrical certificate and can update any onsite electrical works registers.

We try to prevent any disruptions to services during the electrical side of installation projects by agreeing a documented installations plan with Risk Assessments and Method Statements (RAMS). Our teams will start preparatory electrical cabling works during normal working hours and will ensure there is no downtime prior to an agreed cut-over period. At this set time, the server room or datacentre will be powered down by your IT team. Once we get the green light that it is safe for us to proceed, our electrical team will kill power to the relevant part of the room and complete the ‘live’ electrical side of the installation. Once we have completed our testes and restored power, our project manager will give your IT team the ‘green light’ to begin the power-up of your servers and IT equipment.

Your building will be connected to the local electricity supply via a building incomer which will normally provide the supplies to the main HV/LV (high voltage/low voltage) switchboard in your building. This switchboard will provide power feeds to other distribution and sub-distribution boards within your building. A distribution board may be positioned on a floor with a sub-distribution board providing a feed into a server room. Each board will normally have an isolator and ways into which rated circuit breakers can be provided for individual power feeds within the server room including PDUs for server rows, air conditioning, UPS systems and other related equipment. When we survey a building or room for electrical works we normally need access to all the sub-distribution board in the room where we install the kit and may need to follow this back to the distribution board it is fed from and even the main building income and HV/LV switchboard or LV switchboard.
