More and more laws, guidelines and standards have to be followed when constructing electrical systems, including the DIN VDE 0100-410 standard, which requires a residual current device (RCD) for final circuits of up to 32 amperes. This presents a challenge for those planning, constructing and operating data centres. The sensitive triggering characteristic of an RCD clashes with a data centre’s high availability. Can data centres go without the device?
