If you've got a consumer unit with fuses, or even one with trip switches in a plastic housing, you would be safer with a new metal-housed one. We carry out electrical consumer unit upgrade work in Alfreton and surrounding areas.
Why replace a fuse board?
Old fuse boards, as in those actually containing fuses, are much less safe than those with trip switches, or to give them their proper name, Miniature Circuit Breakers or MCB's. Additionally these newer consumer units are much safer as they contain RCD (Residual Current Device) protected circuits. To put it quite simple RCD protected circuits save lives every year. As little as 50mAmps can kill a person. This is why the IEE BS7671 regulations compliance says that all circuits in homes should be protected through a 30mAmp RCD Unit. The device should trip out before the fault current gets to a too-high, dangerous, level. This is why it is vital this component in a consumer unit is fitted and fully working correctly, or this could cost someone their life.
Why are metal housed consumer units better?
Metal clad consumer units are designed to be robust and are perfect for the home. Several household fires involving plastic consumer units brought about the IEE BS7671 Regulation change. From January 2016 all consumer units should be metal clad. Any cables entering into sides of the unit, should be suitably glanded. This is to satisfy the regulations regarding objects not entering the unit, with the added benefit of the cables being tight, so that they cannot be easily pulled out.
Inspection and testing
It's a great idea to have your fixed wiring checked on a regular basis. One of the most important checks is the RCD functionality which prevents electric shock. Another is the correct size of cable to the fuse, or more common now are MCB. MCB's are just a resettable fuse and are much more convenient than a fuse.
If you have the wrong size fuse/MCB connected to a cable circuit, your cables could overheat and set fire to your property. If you are unsure of your installation, it's best to get it checked for safety and peace of mind.
