We receive requests from prospective clients that desire to view AC & DC schematics. There is a lot of valuable information readily available on the web site. However, AC & DC schematics are purposely not posted.

A 120 VAC schematic should show the relationships between all AC sources, (shore power, genset, inverter, ..), selection mechanism(s) (manual, automatic, ...), and galvanic isolation equipment.

The 12 VDC schematic should show the relationships between all DC sources (house battery bank, starting battery, primary and secondary alternators), charging equipment, DC panels, main electric draw items, bonding system, fusing, bus bars, ... The list is extensive and covers many different scenarios. Schematics need to be tailored to the specific configuration. This ensures clarity and prevents confusion. Otherwise, a schematic would need to be very large in size in order to cover every possibility. This would mean that the schematic would have items included that are not installed or appropriate for a given vessel, regardless of size.

As discussed above, ZRD will design schematics for our customers as needed. They are tailored to their specific installations.

We are in the process of publishing a manual covering the electrical basics that all sailors should know. If you desire to be put on a first run list for when it becomes available, please email us (click on the email link shown in "about us" or "contact us" links under the Company section for instructions) using "manual" as the subject line. The best solution involves getting the services of a dedicated, reliable source, such as ZRD to review your situation and desires and recommend an effective and reliable system. This manual will allow you to ask the right questions to the provider of your choice as you go, or with some basic ability and information in hand, you should be able to do it yourself.
