What is a metre box for electricity? This apparatus is primarily used to gauge and keep track of the amount of electricity consumed during a specific time period.
Glass Reinforcement Plastic was used to make it (GRP). Due to its resilience and resistance to fire and extreme weather, this type of material is excellent.
The main switch, metre fuses, and even breakers are all kept in metre boxes together with other electrical parts. Electrical metre boxes are suitable for a variety of installations, including telecommunications and charging stations.
Always locate electrical metre boxes in areas that are simple to access, particularly on exterior sidewalls. Here is a list of the several types of electrical metre boxes available.
Electrical Meter Boxes In One Phase
Meters for single-phase power are stored in single-phase electrical metre boxes. The only bottom-connected energy metre and 1ph +N or 2ph breaker they can support are those. These boxes have excellent electrical insulation and are composed of polycarbonate.
Single-Phase Electrical Metre Boxes Provide Advantages
- They are made of fire-resistant polycarbonate material. This will lessen the likelihood of a fire.
- They can withstand severe weather conditions like wind, rain, and extremely intense sun.
- Because they are waterproof, they shield anyone who comes into contact with the metre from electrical shock.
- They can withstand UV radiation. After prolonged sun exposure, they cannot be harmed.
- They are lightweight, making them portable and making installation and removal straightforward.
- They can withstand shock. Anyone who likes to read the metre won’t be electrocuted.
This kind of electrical metre box is appropriate for locations where you want to correctly measure personal circuits. They could be the circuit of a power system for hot showers, a tiny shop, a small rental space, a hotel room, or an electronic car.
This metre box includes two glass panes, one of which is used to read the metre and the other for circuit breaker purposes. One can seal the windows. This type of metre box is very easy to install.
The entire usage in kWh will be shown on the metre screen. The metre needs to meet the following requirements:
- Voltage
- Currency
- Accuracy
- International Guidelines
- Frequency
Electrical Meter Boxes For Three Phases:
Three-phase metres can fit in this particular style of metre box. Glass Reinforced Polymer is used to make it. The ideal electrical boxes for commercial use, vast farms, and running heavy machinery are three-phase electrical boxes.
They are also appropriate for keeping an eye on particular pieces of equipment in homes or commercial buildings, like a fridge or air conditioner. There are two different kinds of three-phase metre boxes: huge three-phase recessed metre boxes and surface mounted electrical metre boxes.
Direct wall installation of the surface-mounted electrical metre boxes is possible.
They measure 794mm in length, 565mm in width, and 190mm in height. Whether prepaid or smart, they work with all metres. They have many cable knockout positions available.
Glass Reinforced Polymer is also used to make these kinds of boxes. Not simply on the surface, but also during construction, they are installed.
Their measurements are 794mm long, 565mm wide, and 180mm deep. Additionally, they have numerous cable knockout positions.
A Three-Phase Meter Box Installation Procedure:
- The right side of the door should have holes that were pre-drilled before the fitting process, so insert the door’s pins there.
- Place the heavy steel pin into the bottom recess while holding the door upright.
- Place the lower steel pin in the metre box’s lower side’s already-drilled hole.
- Lock the metre box door and keep the keys in a secure place.
