Every residential and commercial structure needs a circuit breaker box to protect its electrical system. Switches, outlets, and light fixtures, together with transition cables, can all be safely stored and easily accessed within their respective enclosures. Cables and wires are safeguarded from outside elements that could cause them to break or create a fire by being housed in electrical boxes. 

Homeowners, especially those who want to do their own electrical work, need to utilise electrical boxes that conform to both national and regional requirements. If you want the work done perfectly, it's best to employ a professional Electrician Freshwater to install your electric box for you. 

Electrical boxes are often made of plastic or metal. Steel, aluminium, and cast iron are the primary components of metal boxes, while PVC and fibre glass are the primary components of non-metal boxes. 

Will switching out the metal electrical box for a plastic one be helpful? 

Before plastic electrical boxes became widely available, metal boxes were the industry standard. A lot of people who have metal electrical boxes in their homes are wondering if they should switch to plastic ones now that they are available for a low price and are simple to install. 

There are many positives to using plastic electrical boxes. 

Electrical boxes made of plastic are ideal for use in private homes. Not only is it inexpensive, but it also saves you the hassle of grounding, which can take up to an hour. This is why most do-it-yourselfers and electrical contractors prefer using plastic electrical boxes. 

A plastic electrical box does not conduct electricity when contacted by a live wire, hence it is not necessary to ground such a box. The plastic electrical box has the additional benefits of being lightweight and simple to install thanks to the inclusion of mounting nails or clamps. 

If the cables entering and leaving the home are not metallic, homeowners can switch to a plastic electrical box. 

Plastic electrical boxes can bend or shatter when subjected to tension, and PVC can melt when subjected to excessive heat. The nail brackets are so fragile that they will not be able to be used for either installation or replacement. 

For what kinds of storage needs do metal bins shine? 

Metal boxes are ideal for securing electrical wiring since they are impervious to fire and extreme temperatures, as well as being incredibly robust and resistant to warping, cracking, crushing, and bending. Metal electrical boxes are more long-lasting, efficient, and durable than their plastic counterparts; hence they are often mandated by local building requirements. DIYers should protect their hands from the sharp edges by wearing gloves during the installation process.

When a metal conduit or metal-sheathed cable enters and exits the electrical box, a metal electrical box must be used. Metal electrical boxes are preferable when installing conduits in unfinished basements or mudrooms with incomplete drywall systems, as well as for other interior exposed applications. Using non-metallic wiring in metal boxes is doable, but correct grounding is still crucial.

Protecting the wiring from the elements by using aluminium junction boxes outdoors is a good idea.
