Old electrical fuse boards can be dangerous. The way we use electricity isn’t uniform, and technology has changed so drastically over the last 2 decades, that we now constantly use devices that were barely even in existence earlier. Televisions are usually mounted, speakers unplugged, and Wi-Fi routers are used 24×7. Along with this, we use mobile phones and laptops that require daily charging.
If your house is old and its electrical wiring hasn’t been changed in a while, there’s a chance it won’t be able to take the electrical load these devices produce. These changes have called for new fuse boxes as well, and it’s important to replace and update yours if it’s obsolete.
