Safely Splicing 220 Volt Electrical Wires and Cables If the original 8/3 cable is fed from the main electrical panel and the neutral wire of the original cable is insulated (it should be), then yes you can bond both the new cables neutral and the ground wires together with the old cable's insulated neutral wire. Safely Splicing 220 Volt Electrical Wires and Cables. Splice large size wires without special tools— insert your wires and tighten the hex nut to make a connection. The Family Handyman editor, Rick Muscoplat, shows you how to splice in jumper wires to give you the slack you need. The wires will bond properly if inserted straight, but you risk making a poor connection if you pre-twist. Guidelines for Splicing Electrical Wiring Electrical Question: I am installing wiring for a hot tub and I did not buy enough length of 8/3 AWG with ground copper wires. https://www.hvacrschool.com/splicing-wires-bad-good-better-best Such circuitry requires you to splice https://www.instructables.com/Master-a-perfect-inline-wire-splice-everytime Knowing how to properly tap into an existing electrical wire in order to add an appliance is an extremely important skill for an electrician, contractor or homeowner. I did not allow enough length for the connections in this box. When working with electrical, you will run into a situation where someone didn’t leave enough slack inside the electrical box. Over time items that use electricity can get a short in their electrical cords and cause the item to stop working or create a fire hazard. It is not uncommon to have the task of expanding an existing circuit in order to add an extra outlet, light or otherwise. Wire splices can be done inside a panel, and often are necessary to repair a double-tap at a breaker (two wires under one breaker connection) using a short wire called a “pigtail,” extend wires that are a little too short when a panel is replaced, or as part of moving circuits from a main panel to a subpanel for a generator switching system. Manufacturers of insulated twist-on wire connectors suggest you not hand-twist the wires together before applying the connector. This is my method to doing a t-splice (splicing a new wire into an existing wire) without solder. I will need to splice additional wire into the circuit, but I'm certain there isn't enough slack to draw the existing line into the fixture's junction box to make the connections. But no matter what the application, you cannot use a u-bolt fitting designed to splice non-electrical cables. From the GFCI box to the hot tub connection is about 20 feet. My dilemma is in adding the fixtures into the circuit between the existing fixture and the switch. Terminal and Splice Assortments Use the included crimping tool to install a variety of terminals and butt splices. If the original 8/3 cable is fed from the main electrical panel and the neutral wire of the original cable is insulated (it should be), then yes you can bond both the new cables neutral and the ground wires together with the old cable’s insulated neutral wire.
