I am assuming the 12' rule of the receptacle placement also applies to a commercial office.
And the # of receptacles on a 20A circuit also applies to a commercial office?
Or both of the above are only for a residential setting?

Thank you
Edward


Thanks

You don't need any receptacles in an office.

Each receptacle in a commercial building counts as 180 VA.

There is no limit to the amount of receptacles on a circuit in a dwelling.

Thanks Ryan.

So in an office situation there is a limit on #of receptacle per circuit.

Yes, an office is a commercial space, therefore the 180VA rule of 220.14 applies.

For example, how many receptacles can be on a 20 ampere branch circuit?
20A*120V=2400VA
2400/180=13 devices on a 20 ampere circuit.

I thought the spacing was 6', and not 12'.
210.52(A)(1) States the spacing to be 6' instead of 12'. Correct me if I'm wrong.

The rule requires that no point on the floor be more than 6' from a receptacle.

If you place the outlets every 12' than no point along the floor line will be further than 6' from at least one receptacle.

Quote
210.52(A)(1) Spacing. Receptacles shall be installed so that no point measured horizontally along the floor line in any wall space is more than 1.8 m (6 ft) from a receptacle outlet.

To be clear for everyone reading this thead, the rules in 210.52 only apply to dwelling units. There are no receptacle spacing rules for other occupancies.

OK, I've not been required to do much in the residential area, so I feel kind of dumb here. So what you're saying is, I can measure any place on a floor, any where in the room, and it should be no more than 6' from a receptacle, OR, is it measured any where along the line at the bottom of the wall, even if you measure from one wall across a corner to another wall, should be no more than 6'?
