[QUOTE="brummydave, post: 479595, member: 18490"] I'm getting confused. Beama expands the 443.4 saying "This means that the electrical installation designer should complete a documented assessment for single dwelling units to determine if the total value of the electrical installation and the equipment connected therein necessitates the cost of SPDs or if the consequential losses are tolerable. This is further explained in IEC 60364-4-44 which states that overvoltage protection is not required for single dwelling units where the total economic value of the electrical installation to be protected is less than[B] five times[/B] the economic value of the SPD located at the origin of the installation." Then they go on to say that "loss of household electronics does not warrant cost of overvoltage protection". So which is it? 5x or not? It's not a bad thing to fit an SPD, and for £20 for a LiVE unit/MCB it's a no brainer? [/QUOTE]
