Question:

2.5 square wire how long is it better?

As the new electric heater wire is too short, can not receive the original 16A socket, so want to wire long, I ask you: 1. How to make a long time can be relatively safe? (Seeking connection method) 2. In the original socket plus What kind of dragline board? (Please recommend the brand and model) 3. Which method is better? Thank you! More

Answer:

With the wire stripping 5-6 cm it, in the exposed about 1 cm to take together, and then around each other, one to the other side of the remaining one on the split around. The wire is made of one or several soft wires, with a soft jacket; the cable is made of one or several insulated packets, and the outer layer is covered with a tough outer layer of metal or rubber. Cables and wires are generally made up of three parts: core wire, insulated foreskin and protective sheath. Commonly used cable features are as follows: CEF - EPR insulated neoprene jacket, marine flame retardant power cable. CVV - PVC insulated, PVC sheathed marine flame retardant power cable. OVC cable commonly used BV, BX, RV, RVV series of wires, including: BV - copper core PVC insulated wire, long-term allowable temperature 65 ℃, the minimum temperature -15 ℃, working voltage AC 500V, DC 1000V, fixed laying In the room, the outside can be deposited can also be deposited.
It is best to change the line, not the same line with the same line after the hook and then solder with solder welding. Plus the mobile outlet, then the bull is better. Welding wiring is better
The easiest and safe way is to buy a standard patch panel, to the big supermarket and other regular stores to buy authentic bull card, the bullet can be the first card. Note that your wall is 16 An outlet, the water heater on the plug to see what is the big, if it is 16 security, then buy a direct 16-inch wiring board can be, if the water heater is 10-amp (2.5 square Of the line, usually 10 An), it would replace the wall outlet or water heater plug, otherwise the size is not the same, can not be inserted.
It is best not to have the middle of the joint with the wire to pick up the wire 5-6 cm it, in the exposed about 1 cm to take together, and then around each other to the other side of the remaining one on the reference map, different Is to buy around the drag line board, then the brand is one, there is not recommended that you choose to switch, the general situation of high-power electrical easy to burn the drag board switch
