Does power have to be turned-off in the server area during electrical installation works?

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.
