Blue Sea Systems Terminal Block 30A 4 Gang – BSS-2504
Keep your marine electrical connections organized, secure, and code-compliant with this compact 4-gang terminal block rated at 30 amps per circuit. Designed for the demands of the marine environment, it provides a clean, reliable termination point for DC wiring runs throughout your vessel — from bilge pumps and navigation lights to accessories and instrumentation.
Each gang accepts a single wire termination, making it straightforward to route and label circuits without the clutter of wire nuts or tape splices. The 30A rating suits the majority of standard marine accessory loads, and the block's compact footprint fits neatly in electrical panels, junction boxes, or behind consoles.
