Electrical Capacity Table
In hazardous (classified) areas, heat produced by current in the wire inside an enclosure is a concern. Therefore, the continuous current of each current carrying
conductor, the quantity and the size of the conductors inside a terminal enclosure need to be limited.

How to use the electrical capacity tables:
In the white area of the electrical capacity table, the permitted numbers of the current carrying conductors inside the enclosure are indicated
(in and out counts as two wires) depending on wire size and continuous current.
In the shaded area of the electrical capacity table, additional conductors/terminals are permitted up to space limit of the enclosure.
In the area with dark diagonal lines, no conductors are permitted.
Jumper links and ground wires can be neglected, in calculating the number of wires. These can be added whenever necessary.
Mixed circuits of different wire sizes and current values are possible by applying the table values proportionally.
Please refer to section 9.3.1 of 8150/1 Installation, Operating & Maintenance Sheet for more information.
