208v Question

[AKelctric]

So I have a Three-phase 120/208 panel, we have a boot dryer for a ski room that has cord end on it, consisting of 2 hots and a neutral.

If I pull a circuit with 2 hots and a neutral to match the cord end, will I still get 208v?

Any input will be greatly appreciated....thank you.

A. If it is really two hots and a neutral and the resistance element is wired only between the two hots, the heater will see 208V instead of the 240V at which it would deliver full output. As long as it is thermostatically controlled all that is likely to do it make it warm up slower.
B. If the heater uses two 120V heating elements, each wired hot to neutral, the resistance elements will still each see 120V and the heater should work just as it would with 120/240 three wire supplying it.

If the third wire is actually an EGC rather than a neutral, then there should not be any connection between that wire and the heating elements, and you definitely have situation A and not situation B.

208 between any two ( or three ) phases.
120 between any single phase to neutral ( or ground )

what is the name plate rating of the boot dryer, you stated you have a boot dryer, and a panel w/ 120/208 3ph, and a cord end w/ 2 ungrounded conductors and a neutral (grounded) but what does the boot dryer require. The cord end should be config. for the equipment it serves.

If it is a three conductor cord - it is unlikely to be 2 hots and a neutral. Following GD comment, the boot dryer is likely two hots and an EGC - no neutral. If the dryer does need a neutral, the cord should be four wire - 2 hots, neutral, EGC.

... If I pull a circuit with 2 hots and a neutral to match the cord end, will I still get 208v? ...

I thinking I don't understand the question.
The panel is 208/120, 3 phase. If you pull 2 hots, a neutral, and an EGC, the line to line voltage is 208V, the line to neutral is 120V. The line to EGC is also 120V. But it would be good if the EGC did not pull any currnet.
