I see the point from the designers view. However, the majority of electrical equipment is intended to be utilized in a 120/240 volt system. For instance, if a 230 volt rated motor is installed in a 120/208 volt system, it will likely work for a short period of time but not as long as if it would...

Rbulsara and Davidbeach thank you for the response. So how is it more economical?......Can you also expand on the following: 1. 120/208 v 4w 3p can be utilized as the main riser??.... 2. Main source?? 3. $/kw - installation cost and even space?? I would really appreciate if a more detail...

Can anyone explain the benefits of utilizing 120/208V 3W 1P verse 120/240V 3W 1p Service Voltages for High Rise Buildings with condominiums? Thank you

We are looking for a transition splice for 3/c PILC to 3-1/c polymeric(XLPE) primary underground cables. The 350 PILC CABLE has conductors of a compact sector shape. We are not sure on how to calculate the PILC insulation diameter for each of the copper conductor since they are not round...

Thank you everyone for the helpful responses.

I am astonish by the diverted responses. I am back to where I started.......

Hello CM3PhaseDesign, Can you expand on your response? It will be an AC power source. Maybe you can explain how 4000 amps came about.. Thank you

Does anyone know how to calculate the ampacity of a rectangular copper bar. Please see the attached drawing for details. Please note that the cupper bar is going to be utilized as a terminal point for conductors up to 600 volts. The terminations will have two hole lugs as as shown on the...

The intent of utilizing the above mentioned electrical voltage/current generator is to generate a voltage/current source with a multitude of harmonic components to test digital meters(based on standard IEC 62053-21). However, It doesn't appear that such voltage generator has the ability to do...

Does anyone have a clue on how to generate a 5th and other harmonic currents with the above mentioned current generator? The user's manuals and technical support have not been of great help. The intent is to generate the 5th and other harmonic currents to test how a given power meter performs in...

It would be a benefit if the word "duct" and "conduit" is clarified by the NESC and NEC.

Can anyone provide feed back on why the NEC and NECS utilize the word "DUCT' and "CONDUIT" differently? It appears to be a contradiction on how such word is being utilized..... please advise

The meter socket is fed from an overhead system.

I indicated above that the meter socket(to metered power) is to be utilized to electrically feed a rectifier unit(for a corrosion protection system, no buildings involved). The question is should the conductors from the service drop point to the service conductors shall be protected as mandated...

It is my understanding that overhead service conductors shall be protected against physical damage as per 230.50 A according to 230.50 B. Recently, an electrician installed overhead service conductors from the service drop conductors to a meter socket on a pole. The overhead service conductors...
