Default underground gas electrical separation ontario

Looking for document with underground gas - electrical separation

Thanks,

Nothing in the CEC. In my province we have a Standata item that says 300mm of compacted soil or separation with a 50mm treated plank.

Let's be realistic; Section 13 can only hold so much data. It's the footnotes to Section 17 where all the action is.

The 1 foot separation is for cable.
In case it applies here ... It's 3 feet separation from the meter (gas or hydro)

You bury the plank?

I don't get the logic in that. Once the wood has the moisture level of the ground it loses any insulating properties.

Treated or not it will not hold up when buried very long.

Strange requirement.

I thought the point of the plank was to let you know before you reached the utilities? If you have the plank on the same level as the pipes and cables, what's the point?

I don't write the rules, I just follow them (occasionally).

Nobody is blaming you for them, they just seem foreign to us.

We don't have the 2X6 exception here, but I'm pretty sure that if you use a plank with 6" clearance, the electrical has to be buried lower than the gas.

The plank helps to stop sparks from the backhoe blowin things up !

I've never used a plank. Not yet anyways. But the code allows PT planks
to be used for mechanical protection. Either PT planks (38mm thick and
extending at least 50mm on each side), or concrete, can be used to
reduce the required burial depth by 150mm. Other methods can be used
to reduce this further.
While the code doesn't seem to specify this, the logical place
for the plank is above the screened material, before the rough stuff
goes in.
Code ref 12-012(2) and (3)
Whether this provides adequate protection over time, I have no idea.
BTW, burial depths without protection vary between 450mm and 900mm
(for voltages less than 750V) depending on things like: cable, conduit,
vehicular areas.

We're talking 2 different things here !

First thing is U/G wiring that is not at required depth, you can use a plank and not have it as deep.

The other is separation between gas and electric, assuming they are deep enough, there are provisions in some provinces to allow them to be closer than 1' (up to 6") if you use a plank

*edit* @PlugsAndLights ... I'd call Hydro One or Enbrigde gas ... they have the final say
