Compatibility / Fitment Guide
| Check | Required specification | Fitment decision |
|---|---|---|
| Electrical system | 12V DC negative-return marine system | Use only where the panel LEDs/backlighting and distribution design match 12V DC. |
| Branch circuits | Maximum 16 circuits with supplied breaker ratings | Match each load, conductor and breaker rating; do not simply use the largest supplied breaker. |
| Panel space | 200 × 239mm face; 65mm depth plus cable bend radius | Confirm the cut-out and rear clearance before drilling. |
| Negative returns | Twelve negative-bus positions | Additional negative distribution may be required if all 16 circuits need separate returns. |
| Installation standard | Properly protected marine DC distribution | Main feed protection, conductor sizing and terminations must comply with the vessel’s design and applicable standards. |
Not suitable for: 24V indicator/backlight installations without manufacturer confirmation, AC mains distribution, more than 16 branches, or locations without sufficient rear wiring clearance.

Frequently Asked Questions
Are circuit breakers included?
Yes. The listed set of sixteen magnetic-hydraulic breakers is supplied.
Does it include a voltmeter or ammeter?
No. 904NM is specifically the no-meter model.
Can I use it on 24V DC?
This listing is the 12V panel. Do not assume LED and backlight compatibility with 24V.
Is the 12-way negative bus enough for every circuit?
Not necessarily. Plan additional negative distribution if your installation requires more than twelve return connections.
Pre-installation check: Confirm system voltage, load current, conductor size, main-feed protection, cut-out and rear service clearance.
