Same story here.
But yeah it's always the plumber who ends up moving because the plumber can cut his lines back and/or extend them wherever he needs to. Mr. Sparky would have to pull all new lines as he can't extend his wires.

Same here. They say it is to prevent a water leak from entering the panel and causing electrocution. Makes sense to me. Gas line and HVAC? Now thats a different ball game of which I know nothing about as far as code goes.

I don't think that is actually listed code in my area but it is in just about every pex manufacturers installation instructions which the code references.

Something I often encounter is plumbing (DWV and supply) running over an electrical panel.

This often sparks the "what came first...chicken or the egg" argument. Around here, the plumber is usually there first, and the electricians fail to avoid their work. But the plumber always ends up moving!

The International Residential Code and the National Electric Code both give sparky dedicated space above his panels, all the way up to the ceiling or the structural ceiling (underside of the floor sheathing above). Nothing but framing and electrical can be directly above the panel...No HVAC, no gas, no plumbing. This is to allow sparky to pull wires years in the future, and to minimize the risk of water saturating the panel. The best way to illustrate the requirement is to imagine the panel sliding upward...It has to go all the way up without hitting your pipes.

The code used to allow you to sleeve the pipes or create a drip shield above the panel. The new electric code has written that out (in 2005 I believe).

Hopefully this will save someone some extra work, since most plumbers don't sit around reading electric code!
Thanks! This is one I haven't heard yet . I'm sure our inspectors will be all over this one soon.

I've never seen a 24" PEX clearance requirement for clearance from heat sources. Uponor/Wirsbo's PEX installation manual states the following:

Do not install PEX tubing within 6 inches [152 mm] of gas appliance vents or within 12 inches [305 mm] of any recessed light fixtures.

That's on par with other manufacturers I've looked up, as well as the PEX manufacturers association installation guidelines.

The electrical code is written to do three things respective to panel clearance.
1) Protect the panel from leaks/saturation
2) Provide adequate safe working space for sparky.
3) Give sparky room to run his wires, and pull wires in the future.

To me, the biggest issue is saturation of the panel. Once a breaker has been wet, it no longer reliably performs at the listed ampacity...Even after it is dried off. Then there's the obvious hazard of water in the panel in the first place.

The other big issue is that sparky can't be squeezed in between gas pipes, water lines, ductwork, or appliances when he's working on the panel. Any of those really up the chances of an electrocution.

One thing I can say is his days of appearing to be a masterful wizard are coming to a close.
The homeowners are no longer impressed now that they know the laborer who was digging ditches last month is now wiring their house.
With supervision of course

It is all about who has the most influence on the code-making panels and who has the largest voting contingent. Fire departments have a biiiiiiiig amount of influence, and tend to vote pro-electric code.
