What the installer needs from you
A marine electrician can build from your package, but only from what it actually says. The more of the design you finish, the less they have to guess, and the less you pay for their time. This page lists what to give them and what to sort out first.
Hand over
- The package. On the Documents page, choose Download everything. You get one zip file with the wiring schedule, the drawings, the bill of materials, the commissioning checklist, the handoff brief and the open-items list, all at the same revision.
- A committed revision. Commit before you hand over, so you and your installer are both talking about "Rev 3", not "the version from Tuesday".
- The printed sheet set. Use Print / Save as PDF under Sheets. The installer works from paper at the boat. A3 landscape prints the labels at full size.
- The handoff brief. It lists the devices you chose, the questions only a professional should answer, and what the design deliberately leaves to them.
Settle before they arrive
- Every shall-level issue. Each one names its ABYC section and says what to fix. Leave one open only if you mean to ask the installer about it, and say so.
- Every run length. Measure them aboard (see "Measuring aboard"). Gauges and fuse ratings depend on length. An estimated length gives an estimated gauge.
- **The values marked
UNVERIFIED.** Confirm them against the boat or the manufacturer's document, or correct them. The surveyor appendix lists every one. - Which fuses are installed. A fuse the design recommends is not fitted until you mark it installed. Tell the installer which ones you want them to fit.
- The names of your circuits. "Bilge pump — forward" is useful to an installer. "Load 3" is not. Names also decide which voltage-drop limit applies (see "Critical circuit" in the glossary).
Ask them to check
The package is design help. It is not an inspection. Ask your installer to check, at the boat:
- every item in the handoff brief's questions;
- anything the open-items list says could not be checked;
- AC wiring, shore power and grounding and bonding, which need a qualified professional;
- the physical route of every wire. WireEngine does not plan wire paths through the boat.
After the job
Ask the installer to mark up the printed schedule with anything that changed. Put those changes into the design, mark the fuses that are now fitted as installed, and commit a new revision. That gives you a record that matches the boat.
