Default How to determine how many divices

What is the most efficient way to determine how many devices are on a circuit? For example if someone asks you to add an exterior outlet in their yard, how would you find out how many devices are on the exterior wall plug circuit to determine whether or not this circuit has room for another device?

Identify the circuit and map it out with a tracer or similar method and then get physical and count 1-2-3...

Kill the circuit and see what's dead.

I don't own a tracer, I do own a toner for low voltage, are they the same thing? I have seen expentice circuit tracers at work but they are upwards of $1000

Yep this is what I would normally do. I was just wondering you guys had any tricks other than doing so.

You can guess and hope for the best?!

But like they all say, kill the circuit, manually search and find everything, map it out.
Double check the same ones after turning back on to be sure it's same circuit and or
you'd have to ohm it all....

You did say efficient, that could mean tedious and lengthy in this scenario.

Have your help do it while you are making money on something else.

Unless it is for any real load just come off the easiest circuit.

Why? Is there a limit on how many devices you can have on a circuit when performing old work?

We have a rule for resi that says twelve locations (receptacles/fixtures) unless it's a known load (LED's, fill your boots).

What happens up there in the tundra, when a 13th is added?

It comes down to the 1 amp per receptacle and 80% circuit loading I would believe.

45 and 69 have always been my favorite two numbers but neither is electrically relative.

The number 69, and the word "relative" should not be used in the same sentence with this crowd.

FWIW...

Yup but besides I don't know a logical reason?
