When it comes to fuse box upgrades ,A4electrical is here to lend you a hand with its team of skilled electricians. Old houses mostly have age-old wiring system and now-obsolete fuse boxes which function poorly to provide enough power supply to latest devices. Even more, these fuse boxes are hardly equipped with electrical safety switches (MCBS,RCBO & RCDS). Outdated fuse boxes are highly prone to short-circuits. Their fuses are more harmful as those fuses tend to catch and spread fire easily. Also there are chances of electrical shock with these old fuse boards. Now, if you want to have peace of mind and safety in your home then a new consumer unit upgrade is necessary. The RCD electrical safety switch, available these days with the latest Consumer Units, makes it sure that you do not get electric shock or no serious physical damage occurs due to a fire breakout. An RCD or RCBO safety switch shuts down the main power supply as soon as it senses the slightest hint of any power leakage from a broken wire or switch within 40ms.
