How to Determine the Quantity of Circuits Your Power Series Requires STEP 1 Figure out how many amps you will be running. An amp is a unit of measure that tells how much electricity a machine is drawing from an electrical system. On your computer or electrical device, locate the faceplate that describes the machine’s technical features. The amps are usually displayed like this: INPUT: 120 V 1.8 A. If you cannot find this ˜ information on the machine, it may be located in the owner’s manual. Calculate the total number of amps per powered series. A powered series is the total number of amps from...

Becoming Familiar with Electrical Systems Most people are intimidated or ner vous when dealing with electrical issues. This step-by-step guide is for people who may not be familiar with electrical systems, but are responsible for specifying such systems when or dering furniture. It provides a basic understanding of an 8-wir e, 4-circuit (20 amp per circuit) system and ho w to specify it on Br etford furniture. By following the simple steps outlined her e, one can easily determine ho w many circuits are required to ensure safety when using electrical equipment. This information is intended to...

Applying Steps 1-5 to Your Bretford Tables and Carrels Now that we know how many circuits each powered series will need, let’s see how it applies to different types of Bretford tables and carrels. Bretford’s 8-wire, 4-circuit system uses Duplex receptacles (each duplex has two power outlets) to determine from which circuit the electrical equipment will draw power. The receptacles are marked 1, 2, 3 or 4 to designate the circuit that is activated when it is installed into the power harness. Circuits 1, 2 and 3 all share a common ground while circuit 4 has a separate ground and a neutral wire....

Here is an example of what a 2-circuit single-faced carrel system will require: (1) 36″W Single-Faced Technology Carrel Starter (1) 36″W Single-Faced Technology Carrel Add-On (2) 36″W Power Harness (2) Duplex Circuit 1 (2) Duplex Circuit 2 (1) Hardwire Power Feed Here is an example of what a 4-circuit single-faced carrel system will require: (1) 36″W Single-Faced Technology Carrel Starter (7) 36″W Single-Faced Technology Carrel Add-On...

Alternatives and Accessories for Power For applications with smaller power requirements, Bretford’s tables and carrels can also be specified with a softwire electrical system. Bretford offers the following accessories for softwire systems: Powerhouse™ This surface-mounted power and data box secures into any grommet hole on Bretford training tables, Legacy tables and carrels, and provides tabletop access to power and data. Each Powerhouse comes with a Duplex electrical outlet, data plates that can accommodate the Amp 110 Connect Series data receptacles, and either a 20-foot or 6-foot grounded...
