We all know that working with electricity is dangerous, yet we fail to realise the risk until something happens for real. Even all those outlets that you use to plug your various electrical appliances can give you a fatal electrical shock if not handled carefully. Of course, working with electrical wires (especially those that have a damaged insulation cover) and any electrical system in general is going to be even more risky.This doesn’t mean that you cannot do simple jobs like changing a burnt up bulb, designing a DIY home automation system or even checking for problems with trip switch. As long as you follow precautionary guidelines to ensure your safety, these jobs pose very little challenge to even those with little knowledge about electrical systems in general.On the other hand, there a few certain tasks that you really want to avoid doing yourself. This is because they are either expensive, require specialised tools or are just deemed to be too dangerous to carry out for those without knowledge and experience working with electrical systems. The following are some of the more dangerous tasks that are best left for prof
essionals, like any reputed electrician Cronulla you can find in your area.
Work on Service Lugs in Circuit Breakers – As we have already said, you can attempt resetting your home’s circuit breakers yourself to find whether there is a short in your home, but you really shouldn’t mess around with anything else you can find in your breaker box. This is especially true of the service lugs and the service cables that are connected to them. These components remain very hot even after shutting down the power delivery to your home, so try to always steer clear of them to avoid injuries
Working on the Periscope – Also known as weatherhead by some people, this is a metal pole that is responsible for connecting your home to the main power line through the utility power lines. This metal pole is dangerous because it often carries a large current, somewhere in the range of 200 amperes, and can prove to be fatal if not handled with care.
Repairing Electrical Appliances – Most people tend to think that it is safe to work with most electrical appliances after unplugging them from the outlet they are connected to. The problem is that this is not always the case: in fact, some appliances are designed in such a way that they will still carry a charge or current inside their circuits for a long time after power delivery is cut off. The best example would be those old CRT TVs we used to have in our homes, which could store thousands of volts inside their cathode rays, providing a powerful shock to anybody who might accidentally touch them.
