1. An electrical cord entry system for a submersible pump, the cord entry system comprising:a receptacle assembly for providing unimpeded transmission of at least one of electrical power and electrical signals through a pump housing of the pump, the receptacle assembly including a ground tab for engaging the pump housing to electrically ground the pump housing. 2. The cord entry system according to claim 1, further comprising a connector assembly for interfacing with the receptacle assembly, the connector assembly supplying the at least one of the electrical power and the electrical signals.3. The cord entry system according to claim 2, wherein the connector assembly includes a splicing member and a single electrical cable coupled to the splicing member, the splicing member including a first portion that couples to the cable with the receptacle assembly and a second portion that diverts a portion of the electrical power supplied through the cable to a pumpage level control device associated with the pump.4. The cord entry system according to claim 3, further comprising a locking arrangement that holds and retains the connector assembly to the receptacle assembly.5. The cord entry system according to claim 4, wherein the locking arrangement includes a cam groove and locking detent associated with the receptacle assembly and a coupling ring associated with the connector assembly.6. The cord entry system according to claim 1, wherein the receptacle assembly includes a plurality of electrically isolated electrical contacts.7. The cord entry system according to claim 6, wherein the electrical contacts have a pin structure with a stepped configuration.8. The cord entry system according to claim 7, wherein the receptacle assembly further includes a receptacle housing having a plurality of holes, the contacts pressed fitted into the holes of the receptacle thereby creating a liquid tight seal.9. The cord entry system according to claim 6, wherein the contacts are formed of brass.10. The cord entry system according to claim 6, wherein two of the contacts are for electrical power transmission and another one of the contacts is for electrical grounding via the ground tab.11. The cord entry system according to claim 10, wherein another two of the contacts are for a device associated with the pump.12. The cord entry system according to claim 1, wherein the receptacle assembly further includes a receptacle housing having a liquid sealing member that sealingly engages an entry port of the pump housing for preventing pumpage infiltration about the receptacle housing into the pump housing.13. A submersible pump comprising:an electric pump motor; a pump housing for encasing the motor; an impeller driven by the motor; and an electrical cord entry system including a receptacle assembly for providing unimpeded transmission of at least one of electrical power and electrical signals through the pump housing, the receptacle assembly including a ground tab for engaging the pump housing to electrically ground the pump housing. 14. The pump according to claim 13, wherein the cord entry system further comprises a connector assembly for interfacing with the receptacle assembly, the connector assembly supplying the at least one of the electrical power and the electrical signals.15. The pump according to claim 14, further comprising a pumpage level control device, wherein the connector assembly includes a splicing member and a single electrical cable coupled to the splicing member, the splicing member including a first portion that couples to the cable with the receptacle assembly and a second portion that diverts a portion of the electrical power supplied through the cable to the level control device.16. The pump according to claim 15, wherein cord entry system further includes a locking arrangement that holds and retains the connector assembly to the receptacle assembly.17. The pump according to claim 16, wherein the locking arrangement includes a cain groove and locking detent associated with the receptacle assembly and a coupling ring associated with the connector assembly.18. The pump according to claim 13, wherein the receptacle assembly includes a plurality of electrically isolated electrical contacts.19. The pump according to claim 18, wherein the electrical contacts have a pin structure with a stepped configuration.20. The pump according to claim 19, wherein the receptacle assembly further includes a receptacle housing having a plurality of holes, the contacts pressed fitted into the holes of the receptacle thereby creating a liquid tight seal.21. The pump according to claim 18, wherein the contacts are formed of brass.22. The pump according to claim 18, wherein two of the contacts are for electrical power transmission and another one of the contacts is for electrical grounding via the ground tab.23. The pump according to claim 22, wherein another two of the contacts are for a device associated with the pump.24. The pump according to claim 13, wherein the receptacle assembly further includes a receptacle housing having a liquid sealing member that sealingly engages an entry port of the pump housing for preventing pumpage infiltration about the receptacle housing into the pump housing.
