Current carrying bolts

With proper conductor cross-section and proper terminal ends (the contact surfaces must be commensurate) you can use the terminal-bolt for the following current rating.

Current-carrying capacity for terminal -bolt*

Ampere	Thread
35	M4
75	M5
125	M6
150	M8
200	M10
350	M12
500	M16

* Bolt is not leading current.

Terminal-bolts from materials like aluminium or copper are not admitted.

* Bolt is leading current.

For the connection torque specification of the terminal boards we can`t give any information, because we don`t know the state of the seat.
