A 20mm 4-way galvanized steel H through conduit box is a type of junction box used in electrical installations to join and protect conduit pipes carrying electrical wires. It has four openings, one on each side, which allows for the connection of four conduit pipes. The "H" shape of the box refers to the configuration of the openings, which are arranged in an H pattern. The box is made of galvanized steel, which provides corrosion resistance and durability. The 20mm dimension refers to the diameter of the conduit pipes that can be used with this box.

A through conduit box is a type of electrical enclosure used to protect and manage electrical wiring connections. The term "through" refers to the fact that the box has openings on both ends to allow for the passage of conduit pipes carrying wires. The conduit pipes are typically threaded on the ends to allow for easy installation and removal.

The 4-way configuration of the H through conduit box means that it has four openings, each located on a different side of the box. This allows for up to four conduit pipes to be connected at the same time, making it a versatile solution for various wiring applications.

Galvanized steel is a common material used in the construction of conduit boxes due to its strength and resistance to corrosion. The galvanization process involves coating the steel with a layer of zinc, which provides a barrier against rust and other forms of corrosion.

Overall, the 20mm 4-way galvanized steel H through conduit box is a durable and reliable option for electrical wiring connections that require multiple conduit pipes.
