    Don’t worry!

    We have everything ready for you.

    Our complete FAQ guide for split bolt connectors will unveil all the information and confusion you have in mind.

    Q1. What Is A Split Bolt Connector?

    A sample Split Bolt Connector

                                                Figure 1: A sample split bolt connector

    It is a small tool having big purposes in mechanical and electrical work.

    They consist of robust materials and can withstand harsh environmental conditions while staying at their place.

    The split bolt connectors come in various shapes and sizes and vary in their uses because of different materials or alloys.

    They are useful because of their simple installation.

    Split bolt connectors do not usually require any expensive tools for working.

    Their small size and durability make them ideal for connecting wires and cables.

    Q2. What Are The Uses Of Split Bolt Connectors?

    A Split Bolt Connector connecting two wires

                                                Figure 2: A split bolt connector connecting two wires

    Split bolts usually find their uses in mechanical and electrical systems.

    Their primary purpose is to connect two wires.

    It consists of two parts: the split and the bolt.

    When you need to splice two wires into a single wire, you hold their ends in the bolt and clamp down the split.

    It creates a connection and makes them stay in place.

    This process is useful when working with electrical appliances in the industry or home.

    Using a Split Bolt Connector

                                                Figure 3: Using a split bolt connector

    The split bolt connectors also find use in other electrical connections for bonding and connecting grounds.

    The different materials of split bolts make them ideal for grounding purposes.

    For connecting wires to an existing power source, split bolts serve their purpose by connecting ground wires, making the process convenient and manageable.

    You can also use them to extend the ground wires by connecting them.

    In the past several years, these connectors are also used to add another telephone line.

    For this purpose, people use a splitter and split the existing outlet into two, and then secure them using a split bolt connector.

    In this way, you can splice different cords into one by using split bolt connectors, which won’t affect the quality of the line already functioning.

    It also saves you some time and money by providing a shortcut.

    Split bolt connectors are also useful in connecting cable lines the same way as telephone lines.

    As many times the cable lines are installed inappropriately, you need to reroute the cable line if you need access to it.

    It may seem to be a complicated process, but split bolt connectors make it a lot easier.

    By placing the split bolts under the baseboard or along with it, they will keep the cable line secure.

    A safe passage will be maintained for the cable to run without any damage to the line.

    Although many people use staples for this task, split bolt connectors are useful if you need to splice several lines together.

    If the cable line is correctly secure, it will stay in place and out of sight, making other house members safe from the wires.

    Q3. What Are The Different Types Of Split Bolt Connectors?

    Split bolt connectors are differentiated based on their shape, size, material, and coating, drive style, finishing, etc.

    The most common types of split bolt connectors are Aluminum, brass, bronze, and copper split bolt connectors.

    ·  Aluminum split bolt connectors:

    Aluminum Split Bolt Connector

                                                 Figure 4: Aluminum split bolt connector

    The aluminum split bolt connectors are heated with aluminum alloy and find their uses in connecting two conductors.

    They are suitable for:

    1. Aluminum to Aluminum Connections
    2. Copper to Copper Connections
    3. Aluminum to Copper Connections

    The tin-plated aluminum split bolt connector consists of high-quality aluminum, which is further plated with tin to increase its corrosion resistance properties.

    The tin-plated is one of the best split bolt connectors to use with aluminum and copper wire connections.

    ·  Copper split bolt connector:

    Copper Split Bolt Connector

                                                 Figure 5: Copper split bolt connector

    The copper split bolts are treated with high-quality copper alloy, called Gunmetal.

    They have excellent corrosion resistance properties.

    Besides, their tolerance to high temperatures and high electrical conductivity make them last longer than many other split bolt connectors.

    These are used in splicing wires, in taps, and for direct burial.

    Besides, you can use them in multiple types of copper wires, including solid copper wires, compressed, compact, rebar, and copper weld conductors.

    You can also use them on aluminum wires safely.

    ·  Brass split bolt connectors:

    Brass Split Bolt Connector

                                                Figure 6: Brass split bolt connector

    The brass split bolt connectors are manufactured from high-quality brass and copper alloy.

    Many companies also use aluminum in the manufacturing of brass split bolt connectors.

    The combination of these materials increases their corrosion-resistant properties, conductivity, and durability.

    They can be coated with tin to make them corrosion resistant.

    However, they are also electroplated with other materials.

    The brass split bolt connectors are compatible with all aluminum and copper conductors and wires.

    · Bronze split bolt connectors:

    Bronze Split Bolt Connector

                                               Figure 7: Bronze split bolt connector

    The primary material used to manufacture bronze split bolt connectors is bronze alloy.

    You can either buy tin-plated or non-tin-plated bronze split bolt connectors.

    The reason for tin plating is to increase its corrosion-resistant properties and durability.

    Many electricians often use them for copper to copper connections.

    These four are the most common types of split bolt connectors used in the industry.

    However, there are many others as well that differ from each other based on their plating.

    The plating on split bolt connectors can be of any type, including zinc, chrome, natural brass, nickel-brass, hot-dip galvanized, bronze, and electroplating, phosphate, electro tin, etc.

    Q4. Do Split Bolt Connectors Have A Limit Regarding The Wires?

    Wires in a Split Bolt Connector

                                                Figure 8: Wires in a split bolt connector

    Almost all the split bolts have a limit of two wires.

    It means you can splice 2 wires under a split bolt connector for wiring and electrical purposes.

    However, you can put a maximum of 3/0 stranded wires under a split bolt.

    It means you can also splice three wires together using a split bolt connector.

    This limit is for both wire splicing and taps.

    Q5. Is A Split Bolt A Wire Connector?

    A Split Bolt Connector as a wire connector

                                              Figure 9: A split bolt connector as a wire connector

    The primary purpose of split bolt connectors is to splice two wires together.

    Thus, as it performs the function of connecting two or more wires, we can call it a wire connector as well.

    Most commonly, copper split bolts are used for connecting a copper wire to another copper wire.

    However, a wire connector and split bolt connector differ in their shape and materials, while the function is the same.

    Q6. What Is The Correct Procedure Of Wrapping A Split Bolt Connector?

    Wrapping a Split Bolt Connector with tape

                                                Figure 10: Wrapping a split bolt connector with tape

    You can wrap a split bolt connector by using high-quality cambric tape.

    We also call it electrical tape because it is polished with an electrical-insulating varnish.

    Wrapping or insulating a split bolt connector is the best choice, especially if you splice wires carrying electrical current.

    Cambric tapes can prevent the split bolt connector from harsh weather, and prevent sparking of wires due to the electrical current.

    The correct procedure of insulating a split bolt connector is by wrapping two layers of varnished cambric tape around it.

    You need to be very careful with the process and make sure to stretch the tape while holding it in your hand, and then wrap it around.

    If you wrap it loosely, the tape won’t stay steady and will look untidy.

    After wrapping two layers of cambric tape, the next step is to cover the spliced wires with four half-lapped rubber mastic tape layers.

    A couple of layers of electrical tape can also be used for the task.

    Q7. Can I Use Friction Tape For Insulating A Split Bolt Connector?

    Yes, you can use friction tape for insulating a split bolt connector.

    Besides, friction tape is also used to insulate electric wires and cable splices.

    It is a strong adhesive tape which consists of a cloth.

    The base of the cloth is made of rubber adhesive.

    That is why it is also called rubber tape.

    These tapes were widely used in the past by electricians due to their thick nature and strong insulating properties.

    However, electrical tapes have now replaced them.

    Q8. Can You Use Copper Split Bolts On Aluminum Wires?

    You can use copper split bolts to connect two aluminum wires.

    However, connecting copper and aluminum wires is not considered to be safe.

    The only safe way to connect them is by using a split bolt connector.

    You can splice both the wires separately to prevent them from corrosion.

    Q9. How Do You Use A Split Bolt Wire Connector?

    A Split Bolt wire Connector

                                               Figure 11: A split bolt wire connector

    We use the split bolt wire connector similarly to other split bolt connectors.
