we now have 240 3 phase service?

Question

we now have 240 3 phase service we have seperate meters for the 240 volt and our 120 volt service we are looking at a building that has 208 volt 3 phase power with 1 meter will our equipment run on the 208 3 phase and why is it all on 1 meter?

Answer 1

I'm not sure why you have 2 meters now. The only 240V 3 phase I've heard of is delta, and you can treat one phase of a delta as single phase and get 240/120V from it. Yours is separate though. Single phase 120 is really 240/120, unless you have a really old single phase service that is just 120. I suppose if it had just 120V and needed to get 240V they could have added the second service for the 240V 3 phase.

Anyway, for your question, the modern method to get a small 3 phase service and still have 120V power, is the 208V Y 3 phase. This has 120V phase to neutral for all the single phase 120V loads. You then have 208V for single phase loads instead of 240V, and 208V 3 phase. There is no reason to have separate meters, since single phase loads can easily be sourced from a 3 phase service. In general, 240V equipment is not made for 208V. A household range is typically rated for both 240V and 208V (less power at 208V). Apartment buildings typically have 208V 3 phase service, even with no 3 phase equipment. Equipment with motors may not work at the different voltage. The nameplate on the equipment should indicate the power requirements.

Answer 2

i'm thinking like "an electrician" interior the previous answer It would not sound like a three-section motor? You did no longer smuggle it abode from the production unit did you? Small autos like that could plenty greater probable be a unmarried section 240V In residential wiring you get the 240V via utilising the two, out of section, a hundred and twenty V materials that residences are under pressure with. you in all likelihood desire a e book (or an electrician) to help you do this the 1st time. on your electric powered container their must be 2 busses and that they are arranged so as that circuits next to a minimal of one yet another are provided from diverse buss A "240V breaker" covers 2 spots and for that reason the two busses. under pressure properly, the 240V is better "section to section" like your nameplate suggested. (-a hundred and twenty to +a hundred and twenty is 240, the two stages exchange oppositely) a very good form of time autos like which may be under pressure 240 or a hundred and twenty. do no longer do something till you be conscious of precisely what you have there! Then get an electrician or a minimal of a e book for some help.

Answer 3

yes but Not as fast or as efficient like trying to run things during a brown out they use one leg of th 3 phs. for 110 .but why is it transferred down to 208 normal is 240?
