2. Choose waterproof cable glands, according to the size of the cable to choose, if the cable is too large, waterproof cable glands can not be installed, the cable is too small, waterproof cable glands are not locked tightly, so the waterproof junction box will not be waterproof.
3. The opening size of the waterproof junction box should be based on the cable glands, which is the same as the relationship between the waterproof cable glands and the cable. If the opening of the waterproof junction box is too large and the waterproof cable glands is not locked tightly, the waterproof junction box can not be waterproof. If the opening is too small, the waterproof cable glands can not be installed at all, which is useless at all.
4. Waterproof junction box and waterproof cable glands material should also pay attention to, nylon general waterproof junction box of any material are well matched, but the metal is not necessarily good matched on the engineering plastic waterproof box, because the thread of metal waterproof cable glands is not long, may not be installed.
