Compatibility / Fitment Guide
Electrical fit: four independent 12/24 V DC loads controlled by SPST ON/OFF switches. At 12 V, no circuit may exceed 15 A and total panel load may not exceed 45 A; use the lower rating imposed by the wire, protection device or connected equipment. Confirm the manufacturer’s 24 V load rating for the specific equipment.
Mandatory external protection: this 4305 panel contains no fuses or breakers. Install appropriately sized over-current protection close to the supply source for every conductor/circuit.
Physical fit: allow 109.22 × 98.55 mm panel face, approximately 95 × 84.07 mm cut-out, 63.5 mm rear depth plus cable bend space, and use the supplied gasket for the IP67 panel-front rating. It is not the 4304 fused panel or 4374 breaker panel.

Frequently Asked Questions
Are fuses included?
No. This is the 4305 switch-only panel; external circuit protection is required.
Can it be used on 24 V?
Yes for compatible 24 V DC loads, subject to the equipment and switch ratings.
Is the rear of the panel IP67?
The panel front is protected when correctly mounted with the gasket; protect rear wiring and terminals from water.
Which switches are supplied?
Four 4150 SPST ON/OFF toggles with 4138 black boots, plus the 4215 label kit.
Important: Circuit protection, conductor size and terminations must comply with marine DC standards. The IP67 claim depends on correct mounting and does not waterproof exposed rear wiring.
