| G-DET-ELEC.2 | All components and equipment will comply with standards established by the EIC project. |
| Children | |
| P-DET-ELEC.10 | Electronics and electronic components shall meet commercial operating environment specifications; critical systems shall consider conformance to industrial specifications, and use industrial/automotive grade components when available and economically feasible. |
| P-DET-ELEC.11 | The detector ground (i.e., Clean Ground) shall be segregated from other equipment grounding. The grounding around the solenoid and the south platform from the detector ground reference, which shall be isolated from other systems and structures and connected to the experimental area ground via six (6) low impedance, insulated 4/0 wires. Other equipment, such as the solenoid power supplies and control systems, shall connect to the experimental area grounding connection separately from the clean ground. All connections shall be effected via low impedance insulated wires (e.g., 4/0). These wires shall have differently colored insulation for easy identification of segregated grounds. |
| P-DET-ELEC.12 | Power supplies (HV, LV, Bias) shall be of the floating type and referenced to the detector clean ground. |
| P-DET-ELEC.13 | Cabling shall be rated to National Electrical Code (NEC) 2020, NFPA 70, UL CL2 or better. Cable jackets shall be marked to UL standards by the manufacturer. Cables rated with the X suffix (Dwellings) (e.g., CL2X, CMX) are not permitted. |
| P-DET-ELEC.14 | Cable routing shall conform to NECA/NEMA 105/2007 for open cable tray systems. |
| P-DET-ELEC.15 | All electrical equipment in the experimental area shall conform to EMI/RFI standards FCC Class B, CISPR11/EN 55011 Class B, CISPR22/EN 55022 Class B, EN 61000-6-3 or equivalent. Exceptions shall be evaluated via EMI/RFI measurement surveys. |
| P-DET-ELEC.16 | Cabinet racks (19 inch type), open or closed frame types (e.g., Hammond C4F247736), shall be COTS and equipped with horizontal and vertical cable managers. These shall accommodate a minimum of three equipment crates or chassis. |
| P-DET-ELEC.17 | Equipment crates or chassis for HV, LV and Bias supplies and for data acquisition shall be rated for a maximum of 2.5 kW each and powered from 120 VAC or 208 VAC 3-phase, preferably. |
| P-DET-ELEC.18 | Any equipment that is powered by a plug and cord shall be either listed by a Nationally Recognized Testing Lab (NRTL) such as UL or have been approved by the Laboratory EEI (Electrical Equipment Inspection) program. |
| P-DET-ELEC.20 | Electrical components shall be derated to 80%, if the manufacturer has not already done so, and if such derating is economically feasible. |
| P-DET-ELEC.19 | Cables shall have sufficient excess length (slack or service loop) to allow connection without strain. Cables outside of the enclosure shall be dressed in a way that allows removal of any module without obstruction, those inside the enclosure shall have sufficient slack to allow visual inspection, connection, and disconnection with all other modules installed. |
| P-DET-ELEC.21 | Enclosures and removable modules should use captive hardware when possible. |
