Load banking a 277volt circuit.

[xformer]

does anyone know an avenue to go about load testing 277V circuits? I am looking for a load I can attach to a 277 volt circuit that would allow me to monitor circuit amperage.

You can easily rent Load Banks.

How many watts?

Dumb question: What are you trying to achieve? You want to load a circuit and monitor how much power your load is drawing? Don't you know that based on the load applied?

Usually load banks are for testing sources, separately derived systems or gens... Not circuits, but you certainly can. Good way to see what it can handle. Better than bridging the gap :/

I get that, but they way the post was phrased wanting to monitor circuit amperage was confusing. Wanting to load the circuit and measure voltage drop, or even IR its terminations and splices would make sense, but the original post didnt.

For small loads, I have used 277V lightbulbs. 100W is available in A19 formfactor, and you can get up to 1500W in linear quartz

I gotcha... plenty of clamp on and hardwire meters to be had. How about a nice clamp on w/a max hold? I read load bank and think something shady is a foot..

I am trying to verify the capacity and continuity of a shared Neutral under full load for the circuit.

thanks n1st.

ah ok that makes sense. I couldn't for the life of me figure out what you were up to.....
