What is an MCB blank used for?
It covers unused MCB slots in a consumer unit, preventing access to live parts and ensuring a safe, professional finish. For metal boards, consider metal blanking plates.
Will this fit non-Whitecliffe boards?
Yes – it is compatible with most standard DIN rail consumer units, but always check dimensions if using a different brand. For retrofit flexibility, pair with our IP40 metal enclosures.
Is it required under the regulations?
Yes – BS7671 requires unused ways in distribution boards to be securely blanked off to prevent contact with live parts. This applies to both domestic consumer units and commercial boards.
