Grounding rebar in foundations

[bdn2004]

We are installing a new pre-fab electrical building on a new foundation. The engineering firm puts on the drawing to bond the rebar to the grounding system. Does the rebar have to be bonded in any certain way?

There are UL-approved connectors for this application. The best is to use exothermic weld (Cadweld), but there are approved compression fittings as well. Burndy makes a wide range of compression fittings for direct-buried grounding applications. Cadweld and/or Burndy will be able to help you.
