Electrical conductors and other materials of proven quality are not enough to make a safe and reliable electrical installation. When performing any task, it is essential to pay attention and have the right tools.


Splicing Electrical Wires and Cables

One of the most important tasks during the execution of the electrical installation is the splicing of electrical wires and cables. Despite being a common service for any good professional in the segment, the task does not should be done in any way, as poorly made splices often result in serious damage and problems with the electrical installation. This work should never be done by amateurs. Splices that are not correctly made can cause energy losses and the consequent heating in the electrical circuit that generates an increase in the electricity bill. In addition, the heating caused by the splices may evolve into a short circuit in the installation and even a fire! 

Splices in low voltage electrical wires and cables can be done in the traditional way (by connecting the conductors directly and covering them with insulating tape) or by usingof pre-insulated connectors.

Splicing with Insulating Tape

Splicing using insulating tape is a more artisanal method and the result depends on much of the electrician's skill, that is, to be safe it has to be done well. The option of using the pre-insulated connectors makes this work easier and more practical, it is less dependent on the electrician's skill and is superior a lot in quality and safety, in addition to reduce the time to perform the service.

Splicing Electrical Conductors Safely

Regardless of the type of splicing to be performed on electrical conductors, it is necessary, first, turn off the main switch, or at the very least, turn off the specific circuit on which service will be performed.

It is also essential to have the right tools for the task and materials such as
quality connectors and insulating tapes that meet the technical standards governing the products and electrical installation.

Never use materials such as adhesive tape, durex or masking tape to splice wires, cables and electrical appliances, as they are not manufactured for this purpose and compromise too much the electrical installation safety. Among the tools used for this job are:

  • Universal stripper pliers
  • Cutting pliers
  • Personal protective equipment (PPE) such as gloves and goggles.

The stylus must never be used to strip electrical conductors, as it is a tool flexible and fragile for work of this type. In addition, it can cause personal injury with more ease and cause damage to the wire or cable, particularly accidental cuts in the insulation of the product.

Traditional Amendments (with tape)

They are made with electrical tape. In this case, the electrician must pay extra attention when making the amendments so that the conductors are well attached to each other.
One of the ways to make these splices is to strip the ends of the two conductors in more or less 5 cm each. With the pliers in hands, the electrician holds the end of a cable and with another hand he twists the conductors until the splice is very tight. Then, you must pass minimum, three layers of electrical tape so that the wires are completely insulated.

Splices with Connectors

It is a more practical method for splicing electrical wires and cables. In that case, just just remove the insulation (and cover, if there’s any) and fit the conductors into the connector following the supplier's recommendations.
As they are pre-manufactured, these connectors reduce the risk of splicing errors and also allow faster execution of this type of service.

This step makes the installation more reliable and makes the owner safer, because in addition to have a qualified professional for installation, you will have a product made for it that reduces even more the possibility of human errors and short circuits.

safe and reliable system.
