5 Things to Know Before Buying BS Standard Cable 

Mingda supply professional and honest service.

Electrical wiring helps power everything in homes and offices, making it helpful to identify its uses and attributes before buying to ensure you choose the right option. These wires are often confused with electrical cables, so keep in mind that electrical wires consist of a single conductor, while cables hold multiple wires. Learn the uses for electrical wiring, when to replace them and a few attributes to consider before buying.

Electrical Wiring Uses

The purpose of an electrical wire is to distribute power by transmitting electricity from a transformer or another source to an outlet, device, cable or socket. This wiring conducts electricity while providing a low-resistance path for electricity to flow through. Here are some types of electrical wires and their uses:

• Single-conductor wires: The most common electrical wire, this option comes in stranded and solid variations. These wires are often found in common electronics, like chargers, due to their flexibility.
• Multiconductor cables: Multiconductor cables are used behind the walls of a home or business to connect heavy appliances like dishwashers and washing machines. Also referred to as nonmetallic, these electric cables are covered in black sheathing.
• Metal-clad cable: A metal-clad cable is housed in a spiral metal casing and is primarily used in industrial applications due to its ability to bear heavy loads. Its metal casing also offers protection from wire failure, reducing fire risks.

When to Replace Electrical Wires

Here are some signs you should get new electrical wire:

• It is over 30 years old.
• It trips the breaker.
• It requires extensions.
• It causes power surges.
• It creates a fire risk.
• It causes lights to flicker.

Purchasing new wires is also beneficial because they are insulated with higher-quality materials and will typically last longer in harsh environments compared to older, black rubber wires.

Electrical Wire Considerations

Consider the following factors when purchasing new electrical wire:

1. Copper Price

Copper is a commodity on the NYSE which means the price goes up and down daily. The price of copper electrical wire changes daily with the NYSE price which means you can plan your purchasing times. Similar to buying real estate when prices are down, it&#;s a good idea to buy electrical wire when prices are down as well.

2. Voltage

Hook-up wire is typically rated for 300 and 600 volts while portable cord products are rated for 600 and volts for different applications. Remember to check the voltage of the application and make sure it matches your cable selection. Getting a cable with higher voltage capabilities means it will be more expensive.

3. AMPS

AMPS, or Amperes, are calculated through an equation that meets the NEC or National Electric Code. Not only do you need to know the calculation but you also need to know if it meets NEC approvals. Speak to an electrician, and they will let you know what AWG-size electrical wire you need based on the amount of voltage and a few other factors.

4. Temperature

Most building wire is rated for 90°C to cover 90% of the home and building temperature ratings. However, some types of hook-up wire increase in temperature for applications that require the wires to sit in high heat. Standard PVC wire is rated at 105°C and PTFE wire is rated for 200°C. Buying the wrong electrical wire could limit the longevity of the insulation.

5. Protection

The protection lies in the jacket covering the copper conductors. Romex® electrical wire is manufactured with less protection, but it is priced right for indoor applications. UFB cable has a very strong outer jacket that covers each conductor individually so that it can be installed directly in the ground without conduit.

6. Approvals

Approvals make the inspectors happy because there is a third party that double-checks the voltage, temperature and protection capabilities. Those third-party approvers are UL (America), CSA (Canada), CE (Europe), MSHA (Safety) and RoHS (Lead-Free). These approvals ensure inspectors that your electrical wire is manufactured to a standard and double-checked by a third party.

7. Flexibility

Solid, stranded and flexible. If an 8 AWG wire has one strand it&#;s less flexible than an 8 AWG wire with 19 strands. A flexible 8 AWG wire would have 133 strands. Therefore, as long as you&#;re comparing the same AWG wire then more stranding is equivalent to more flexibility. The jacket insulation can also help with flexibility because rubber insulation is more flexible than PVC insulation. Typically, more flexible cables are more expensive because the stranding and insulation are a bit more complicated.

Wire selection is a critical piece of electrical assembly design as it affects the safety, functionality, ease of use, and serviceability of the assembly.  There are several factors to consider when choosing an electrical wire or cable. However, the most important factor to consider is the electrical requirements of your application.

While all applications are different, there are some basic things to know about electrical wire when deciding which wire is the best for your application.

1. What size wire do I need?

There are two aspects to consider- thickness (gauge) and length. To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it.  The distance you need the wire to go can also impact the gauge of wire you need. The longer the wire, the more voltage you can lose through resistance/heat. You can counteract voltage drop by increasing the wire gauge (the gauge is increased by lowering the number) which will, therefore, increase the amperage capacity. 

2. How flexible should the wire be?

There are 3 main categories of cable flexibility:
Solid core &#; almost no flexibility in lower gauge wire
Coarsely-stranded wire &#; moderately flexible
Finely-stranded wire &#; highly flexible with frequent flexing or tension, you&#;ll want a cable that is finely stranded and has a high durometer like:

Additional sub-categories of flexibility in cable include Stationary, Hi-Flex (Bending Flex), Continuous Flex, and Torsional Flex (used for robotic applications).

3. Is wire insulation needed and what type?

The assembly&#;s working environment should determine the type of insulation your wires need.  Types of insulation vary by the type of electrical wire. Often insulation will vary to alter performance in certain environmental conditions, or to make the wire easier to work with.

 When deciding the insulation there are some things to consider:

Voltage and Ampacity &#; the higher the voltage level, the thicker the insulation needs to be to reduce the risk of shock.  Ampacity required determines on the size of the wire and the run.

Environmental considerations &#; exposure to the sun and UV, extreme temperatures, presence of harsh chemicals or oils can impact performance. Do you have harsh chemicals in your plant? You&#;ll likely want a cable such as this:

Or

Abrasion/Impact resistance &#; looking for a cable that might need to be protected from impact, like getting hit or run over? You&#;ll want to consider a cable with a thick, reinforced jacket. Such as this:

Coating &#; some coatings can make it easier to print on the wire or push/pull them through conduit

4.  Do you have a wire color standardization?

Many companies use standardized wire colors to denote hot wires, ground wires, and neutral wires; some will even color code the different circuits within an electrical assembly. This variation of colors assists with troubleshooting while reducing safety hazards.

5. Does your equipment require specific cables?

MISUMI offers Equipment Specific Cables for transmitting communications and optical signals and connect between devices, such as computers and displays.

IEEE CableConnection Cable for Terminal Block Conversion Units

Construction and material details vary by application, with differences in transmission quality, durability, etc. The ends of the cable feature connectors and sockets according to application, such as connectors for motors and solenoid valves, or for image and sensor transmission.

6. Are there problem areas with re-occurring failures?

When choosing the right cable for your problem area, you must first ask yourself why the cable is failing and how often it disrupts production? If your answer is often, it&#;s time to look for a longer-lasting product.
