Grounding Audit Client Name – Facility Location

Executive Summary

The following document presents the results of a site grounding audit performed by Jesse DeBoom with Interstates on Date. Site Escort from Client Name in Facility Location was the facility’s escort during the onsite grounding audit. Recommendations were created from these results to ensure safe grounding of equipment throughout the entire facility. During the onsite grounding system audit, we tested 287 points. These points included, but were not limited to, items such as ground whips, electrical equipment, building steel and equipment structural steel. Overall, the grounding system, which could be verified, seemed to be in good condition. All systems, which should be connected to the grounding system, were connected at the Facility Location facility. There was 1 point tested which had a High Ohm reading, and 15 points tested which had a Critical Ohm reading. There were also 10 points tested that would not produce a reading, indicating there is no or an extremely poor ground connection. Recommendations for the 26 points indicated above and any additional grounding issues noted while on site have been made below.

Scope of Work

This grounding audit is being undertaken at the request of Client Name to analyze the grounding system in the facility in conjunction with safety standards. The scope of work for this project was to complete the following: 1. Confirm that systems which should be grounded are grounded. 2. A visual inspection of the current grounding of the system. 3. Ground resistance tests via a clamp on ground resistance tester to be taken at any available ground whips and rods going to ground. 4. Ground continuity tests via a point to point continuity tester to be taken at all available gear going to ground. The following is a list of equipment tested: Switchboards, Switchgears, Conduit, Stand Alone Starters, Process equipment, Exposed Structural Steel, Electrical Outlets, Junction Boxes, and Portable Process Equipment 5. A written report with recommendations based on the results and observations. 6. Provide planviews to indicate the area in which test points were taken. 7. Test point tables to indicate all recorded measurements.

Clarifications

Analysis Using an AEMC Model 6424 Ground Tester (Test Current: 200mA – 250mA), the continuity between two conductive parts or the continuity to a main earthing terminal was measured at all major pieces of equipment in the electric rooms and most of the equipment in the production areas. This was done by using a known ground reference and confirming the continuity between the ground reference and the piece of equipment being tested. This confirms that the equipment in question is connected to the grounding system.

Using an AEMC 6416 Clamp-On Ground Resistance Tester (Test Current: 1mA – 30A), the resistance to ground was measured at all accessible ground whips. A clamp-on ground resistance meter is effective in measuring the resistance at any point in the grounding system to earth but will not provide accurate readings if the meter is measuring a closed loop of the grounding system. However, for the purposes of this audit, this method was sufficient in identifying points where a grounding connection was ineffectively grounded to earth or was disconnected from the ground loop. The recommended standard target for grounding is 5.00 Ohms or less for ground resistance which is under the NEC required value and 0.50 Ohms or less for Point to Point resistance. The planview drawings in Appendix A: Planview Drawings indicate all areas where grounds were tested, and Table 1: Test Point Table indicate the ground resistance and continuity values that were measured. In regards to the magnet equipment, issues were found on site and suggestions, as well as actions, were discussed on site to remediate the bad ohm readings. The system was grounded from the steal frame with no jumper from the already solidly bonded frame to a steal handguard. A jumper was installed to properly ground the frame, the metal detector, and the surrounding chutes.

Conditions The Ambient Temperature of the areas on the days the grounding audit was conducted are as follows:

• Electric Rooms: 75° F • Outside Areas: 45° F • Bagging/ Production Area: 65° F • Warehouse: 85° F

Section 2: Test Point Tables

The following tables show the values measured at each grounding test point. Note that some of the test points in the tables correspond to a point on the drawings of Appendix A: Planview Drawings . Note: Points with a value of N/A under the “Test Value (Ohms)” indicates a po int that did not give a reading when tested. Points with a value of N/A under the “Grounded Circuit Used” column indicates a ground whip connected di rectly to the grounding system.

Below is a chart to that indicates recommended guidelines on equipment tested for continuity and resistance.

Severity Criteria – Ground Resistance Measurement Ground Resistance Resistance Measurement

No deficiency
