Usually, it is not allowed for two wires to be connected to a cold crimped terminal. When it is necessary to use a special terminal for crimping two wires due to terminal limitations, it is advisable to use a special terminal for crimping two wires first. Otherwise, it is advisable to use a cold crimped terminal that is larger than one or two levels

Two wires are not allowed to be connected to one cold pressed end because both wires are pressed in at the same time, and the insulation skin of the wire cannot enter the insulation sheath of the cold pressed end. Therefore, the wire will expose the copper wire, resulting in poor insulation.

Generally, the use of OT cold pressed terminals requires wire diameter requirements. 10 square meters is 10 square meters, and 16 is 16, all of which are dedicated. If you use a 10 square OT to press two 10 square wires, the T-wing is not enough to accommodate it, and the operating process stipulates that it is not allowed to connect two wires, which refers to the situation where the same wire diameter is used. If you use a 10 level OT to press two 4 level wires, it is possible.

Double line OT copper nose, T-wing needs to grow much longer, and pressing two wires at the same time can fully accommodate it. For example, for an OT with a single wire of 10 square meters, pressing one 10 wire is just right, but pressing two 10 square meters won't wrap it. And the OT of double line 10 can compress two 10 flat lines.

If there are no dedicated terminals for crimping two wires, both wires can be crimped onto cold crimped terminals and then pressed onto the terminal block. If each wiring point exceeds two wires, the terminal block can be short circuited with short connectors to increase wiring points.
