Is there a code requirement to pigtail an electrical system with aluminum wiring?

The mix of Copper & Aluminum is a concern....

Typically the breakers and bus bars were listed for use with both Al and CU.

That would be correct Joe. I have seen reports where the AL was on a breaker and the suggested "fix" was to pigtail copper. This was an unnecessary step as the breaker or bus was already listed for use with the aluminum.

The only guidelines would be the manufacturer's instructions on the package?

Could you expand on why the pigtailing was requested?

Unless the devices are listed for use with AL there would need to be a method like pigtailing. The simple existence of AL does not require pigtailing. There are also devices that are listed for use directly connected to the AL.

The answer is no.

If you are asking does code apply if you do pigtail, which is an entirely different question, the answer would be yes.

It would need to be done in accordance with any listing or labeling requirements.

Apparently, I misunderstood the question.

It is not required that AL wiring be pig tailed with CU - that's what I thought the question was.

If the AL is pig tailed with CU, the connectors must be appropriately listed, and used in accordance with their manufacturer.
