Electrical – Main electric service & range hood vent

electricalventing

I'm in the midst of a reno on my kitchen, which involves some reconfiguring of the placement of appliances. As a result, where the stove is going – and hence the range hood / blower vent location would come through the roof right near where the main electrical service attaches to the house and runs to the main panel.

My question is this: is there a minimum recommended / required distance between the range hood vent location and the main electrical connection coming from the utility to the house (I'm in CA if there's state specific code on this)? Its a very shallow pitch roof so I'm unable to elbow & run the ducting through the attic to come through the roof elsewhere. If I need a minimum separation I'll probably have to run a chase along the ceiling inside the kitchen to come through the roof far enough away from the electrical main.

Thanks for your help.

NEC 110.34 (F) says, "pipes or ducts foreign to the electrical installation and requiring periodic maintenance or whose malfunction would endanger the operation of the electrical system shall not be located in the vicinity of the service equipment, switchgear, or industrial control assemblies. Protection shall be provided where necessary to avoid damage from condensation leaks and breaks in such foreign systems..." Beyond this, I don't see anything else in the NEC that might speak to your issue. It doesn't sound like your installation plan would endanger the operation of the electrical system, but that is a question you will have to answer. I did a web search for California building codes but turned up nothing that specifically addressed your situation.
