How can you know the sizes of copper busbar you need ?

Referring to the current form, you can choose the suitable width and thickness you need , whose current capicity should at least equal the current you used in. It would be better to choose the sizes with higher current capicity to control the temperature raise of busbar in using. Then you can confirm the hole center distance by measuring the screw center in actual use in equipments.

Then you can send the basic datas according to the drawing offerd as a normal flat copper busbar. Quotation will be sent with datas you offers.
