The work required to install the necessary power and ground can be completed simultaneously with the relay rack installation. You may elect to hire an electrician to complete the work. In general, allow two weeks from your customer commit date (CCD) to complete any stand-alone power and ground work.
- The amperage, number and type of receptacles will be determined at the site survey.
- Dedicated circuits backed up by UPS/generator systems are strongly recommended.
- For AC power, 20A, 120V AC generator-backed, AC power is typically requested.
- For DC power, if 48VDC, end user must provide +/- power leads with 2m (-6’) of slack wire coiled at the equipment location.
- You must provide adequate grounding capability in the form of 19mm (¾”) metallic conduit from the equipment to an approved building ground.
Grounding options listed in order of preference are: building service ground, main electric box, building steel, and, lastly, a metallic water pipe which is in direct contact with the earth for 10’ or more and electrically continuous to the point where the protector ground wire is installed; a bond must be placed around any meters.
