Limitations of an Eruv

Question

Are there any limitations to what you can carry or where you can carry within an eruv on Shabbat?

Answer 1

Anything that would be useful for use on shabbos you can carry within an eruv (if you follow the local eruv)

The Greater Boston Eruv Corporation's "Halakhot of Eruv" page has a section on the limits of Eruv use including the following three main points:

• Even within an Eruv, one may not enter non-Shabbat-compatible buildings (e.g. stores) on Shabbat.

• Even within an Eruv, one may not engage in non-Shabbat-compatible activities (e.g. gardening) on Shabbat.

• Even within an Eruv, one may not handle Muktza items (e.g. a hammer) on Shabbat.
