how many electrical wires can be tied.together
According to https://www.bkironwire.com/Twisted-Wire-pd40745850.html (NEC), the standard for building electrical systems in the U.S., only three wires are allowed to be joined together. This is clearly stated in section 310.15 of the NEC, claiming that conductor bundles must not exceed three conductors.

With a few key considerations in mind, it's important to avoid bundling too many wires together. Excessive cable congestion can create a fire hazard, induce overheating, and be a potential tripping risk if the wires are not suitably fastened.

With respect to the amount of wires that can be connected, the NEC does not sate a precise number; yet, it's generally accepted that three is the most acceptable figure. It is thought that this is derived from the concept that NEC sets a limitation of three conductors on wire collection.

Despite the general rule, a number of scenarios allow the use of wires in specific applications. One example includes wiring used for low-voltage items like doorbells, intercoms, and other security systems. The other exception lies in settings that call for wires to handle high-voltage services such as electric fences or power lines with elevated voltages.

To err on the side of caution, it is in one's best interest to limit any grouping of conductors to no more than three. stainless steel wire cutters is advised by the National Electrical Code (NEC) and can help diminish the possibility of fire or other high-risk scenarios.
