Hi,

I don't have my code handy and just wondering how many plugs you can have on a 14/2 circuit in a parking lot? How about if the circuit is controlled by a timer?
All plugs are used for engine block heaters.

thanks

Put as many plugs out there as you want. Absolutely no restrictions on that. There are limits on receptacles, however.

Hi
We usually do one 15a cct for 2 cars. Nowadays, with diesel trucks everywhere, they can easily use up a 20a cct by themselves. (Depends what the owners have added) eg oil warmer, battery blanket, circulating heater, ....

How many parking spots are there? You need one circuit per spot, only one duplex receptacle per circuit. CEC 8-400

It's common to use one split plug for two stalls.

Are these receptacles metered such as in dropping a $1.00 in the machine for 3 hours of electricity.

No
They are a power management system. They can be programmed for temperature, duration and power limiting.
And, I'm not 100% sure, you can read the power consumption.

Is there such a thing as public receptacles for engine heaters? How do they bill for electricity.

Might be worth designing a parking meter like head that accepts coins and CCs in exchange for power

Yes and no. You can't pull into Walmart and plug your car in.

Most employers will install receptacles in the parking lot for there employees use.

You will also see them in parking garages where you pay for the parking spot.

These are almost always installed in the cold of winter, and never in the nice weather of summer.
