Part numbers 5056100 / 2356100 utilize yellow wing-screws that can be manipulated by hand, and comply to the following: ABYC E-11.4.23 states: Panelboard - an assembly of devices for the purpose of controlling and/or distributing power on a boat. It may include devices such as circuit breakers, fuses, switches, instruments, and indicators. ABYC E-11.4.27 states: Readily Accessible - capable of being reached quickly and safely for effective use under emergency conditions without the use of tools. ABYC E-11.9.1.2 states: A panelboard shall be installed in a readily accessible location and shall be weatherproof or be protected from weather and water splash. The ST-Blade Water-Resistant Fuse Blocks and Busbars are rated IP66 and withstand water from heavy seas or projected in powerful jets, allowing for flexible installations anywhere on boats or vehicles.
