designing and installing a new
electrical
system in your home is one of the more complicated elements of the overall building project.
Most renovators, faced either with historic electrics untouched since the era of bakelite’s dominance (if not before) or, perhaps worse, ‘improved’ and amended over years of previous owners’ marginal projects (closed off faceplates and switches that don’t work being classic signs) will also be keen to bring things up to date. For those of us who didn’t listen much in physics classes, the world of electrics can be quite scary and for most, the services of an electrician are essential.
Understanding the main components of a residential electrical system and how they work together to supply your home with energy can help you spot potential issues more easily.
Earthing is a fundamental safety system used in electrical installations. It works in co-ordination with circuit breakers mcbs , fuses , and rcds to ensure that an electrical supply can be disconnected quickly in the event of a fault. This greatly reduces shock risk. Most houses have an earth connection supplied by the electricity supplier. Those that don't (generally country houses several miles from the nearest town), use a local earth rod instead. The supplier's earthing terminal or your own earth rod is connected to the cu earth block. Each electrical circuit in the house takes its earth connection from the cu earthing block.
When assessing any older home, it’s wise to look for jury-rigged electrical work done by an earlier owner. Many of these mistakes are obvious—like basement outlets that don’t have cover plates, or romex cable that’s exposed on the wall. But there are other unsafe retrofits that only an experienced electrician or building inspector can identify. If you’re the new owner of an old house, it’s smart to hire a professional to thoroughly inspect your electrical system.
Understanding Your Home Electrical System
Electricity plays an essential role in how your home operates. Whether watching tv, powering heating and cooling systems, or charging a cell phone, we rely on our home’s electrical system to provide us with power when and where we need it.
By understanding the basics of how electricity is distributed around your home, you can keep this important system properly maintained and in safe working condition:
electricity enters your home through a service head from a series of outdoor power lines or an underground connection. A typical service head consists of two 120-volt wires and one neutral wire that deliver power to lights and appliances around the home.
