Good point Ray. I work on lots of low budget micro remote systems too.....decent ATC fuse blocks are avaiIable (though I avoid Autozone etc) and you can mount 'em in a gray metal box to look code-ish Have done marine disco (big red switch) and class t fuse in some tiny systems for inverter -- the Morningstar Suresine inverter is a 300w beaut for many such applications. The real b***h for the tiny stuff here has been battery chargers for small electronics, they cost outrageous prices for a 12VDC charger for many gadgets. Easier to add the small inverter at some point, and then maybe just go all AC in the future, as the4 120 vac chargers usually are included with the gear. Somewhere I have notes from a worst case scenario job I did on this a few years back.... The special chargers added up to 3 times the cost of the inverter. They had a bunch of portable radios for a fishing lodge.<div>

The problem with many of the suggestions, is that these Micro 12 v systems generally have budgets under $1000 parts. 20% of the budget allocated to breakers and discos isn't reasonable, same with a Trimetric.<br>
The ATC fuses are used for literally billions of 12 v circuits that all of you use every day. (in your cars)<br>
If the budget has that much in it for fusing, then I'd be pushing for an inverter, as the customer will be much more satisfied with the appliances available and the over all versatility of the system.<br>
These days, economics is the only real advantage of DC only systems. Most of my DC only systems ended up adding at least a cheap inverter later, might as well do it right the first time.<br>
