Electrical supplies are a must have for any homeowner or a property owner. It is not just about the spare lights and appliances, but also about the wires, switches and distributor devices. In case of any breakdown, it is, however, is your best interests that you call your electrical expert, but you will still need to keep your supply handy.

There are a few key considerations to keep in mind before buying electrical supplies. The following section of the article lists the seven most important things to remember while purchasing electrical supplies.

The Input and Output Voltage Ratings

While buying any electrical device make yourself aware of the voltage rating of the equipment. It is imperative that the voltage rating of the device should match with the main input line inside your property. In case of electrical fuse, circuit breakers and transformers, if you use incorrect voltage rated equipment, you run the risk of electrical fires, short circuits and arcing.

About Continuous Current Ratings

Check for the continuous current rating for devices like a circuit breaker. The continuous current rating measured in Amperes is the representation of the continuous current that is supposedly carried by the device at a precise ambient temperature. It determines whether or not the device will function properly in various environmental conditions.

The Short-Circuit Rating

The SCCR or the Short-circuit current rating is the maximum amount of current the device can handle adequately. This is important when you have many devices connected to the same source. Such an assembly needs proper monitoring and maintenance. Being aware of each device’s SCCR will help prevent short circuits and device damage.

The Electrical Current Frequency

You also need to evaluate the device based on the current frequency they are operational at. This is true for most of the circuit breakers that are installed on a property. This, along with the SCCR helps determine the maximum current load the device can carry.

The Maximum Interrupting Rating

This is also known as the interrupting or the breaking capacity. The MIR is the rating of the current at which the device will develop a fault or get short-circuited. You need to check for the maximum fault current that is generally delivered at your location since AC lines do tend to fluctuate depending on the supply and usage. Once you know the figure, you have to select your device accordingly.

Various safety concerns

As you can see, the safety of you and your family members concerning electrical devices are dependent on multiple factors – the current ratings to the breaking capacity, even the location of the property. This is the main reason why a proper construction, set-up, design and maintenance is required while provisioning the power/utility lines as well as the equipment.

Never forget the Quality Assurance (QA)

Always make sure that the device or product you buy has undergone rigorous testing concerning its health and safety features, performance as well as durability. The seller usually provides proof of quality through a registered seal of assurance or certifications.

Keep in mind these seven key facts while purchasing any electrical item.
