Wiring Direction: Wiring between the main circuit breaker and each branch circuit breaker in the box generally goes on the left, and the wiring out of the distribution box generally goes on the right. Binding Requirements: The wires should be bound with. BARTEC stainless steel housings and distribution boxes are designed and approved for Zone 1 and 2 as well as Zone 21 and 22. They are particularly suitable for applications under extreme environmental conditions, and they provide reliable protection under heavy loads. Contact Surface Treatment: Coatings or oxide layers should be removed from the connection area to expose the natural metal and reduce contact resistance. Due to the high hardness of stainless steel, drilling holes later is not only laborious but also easily damages the anti-corrosion layer. We. A distribution box is a low-voltage electrical enclosure that receives incoming power and distributes it safely to multiple outgoing circuits through protective and switching devices such as MCBs, RCDs, RCBOs, fuses, isolators, busbars, neutral bars, earth bars, and surge protective devices. From cost-effective indoor solutions to corrosion-resistant options for harsh environments, our range ensures durability and reliability across diverse applications.
