Egis RT Fuse Blocks: 8025, 8026, 8028 & 8029 Parts Guide

Adding a fused 12V or 24V accessory distribution point to an RV? The Egis RT range offers six- and twelve-output fuse blocks with clear covers and blown-fuse LED indicators. The key choice between 8025, 8026, 8028 and 8029 is whether you need six or twelve fused circuits and whether a separate ground-return section should come with the block.

Which RT block includes a ground-return section?

The fuse block carries the positive branch supply through individual blade fuses. The ground-return section is a separate set of negative connections; it is not another bank of fused positive outputs.

Egis 8025 vs 8026 vs 8028 vs 8029

Egis part Fused outputs Ground return Block design
8025 6 Included 12-position section RT ATO/ATC with clear cover and blown-fuse LEDs
8026 12 Included 12-position section RT ATO/ATC with clear cover and blown-fuse LEDs
8028 6 Not included RT ATO/ATC with clear cover and blown-fuse LEDs
8029 12 Not included RT ATO/ATC with clear cover and blown-fuse LEDs

These RT blocks are designed for nominal 12V or 24V DC systems, with a manufacturer-stated operating range of 0–36V DC. Egis specifies 100A maximum for the complete block and 30A maximum per circuit. They accept ATO/ATC/ATF blade-fuse types; although the factory describes a range of available fuse sizes up to 40A, the block's 30A per-circuit rating and the connected wire and equipment ratings must still be respected.

The manufacturer lists two spare-fuse holding locations per six-output module. These are storage positions rather than additional energized circuits. RT blocks use ring-terminal output connections and stainless self-locking hardware; the covers help protect the connections and provide space for identification labels.

Choose by function, not appearance: 8025 and 8026 include a 12-position ground-return module, which Egis says can be detached for different cable routing. The 8028 and 8029 omit that module. If your installation already has a suitable negative bus, a model without the extra return block may be preferable.

Factory specifications and installation details

Egis documents the configurations and ratings in its RT ATO/ATC fuse-block range. See the manufacturer's 8025-series example and 8028-series example for details about removable ground modules and blown-fuse indicators.

Electrical installation: A fused block does not replace the need for properly sized source protection. Match fuse, cable, circuit load, mounting location and connection hardware to the manufacturer's instructions. Disconnect all battery and charging sources before electrical service.
