  8130.2F, CHG 3, page 155: "(6) System controls (for example, fuel selector(s) and electrical switches/breakers) are appropriately placed, clearly marked, provide easy access and operation, and function as intended by the builder/owner."
 
 The link for the full document is http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgOrders.nsf/0/1ba6ee60e8779bd7862572c90063c0ac/$FILE/Order%208130.2f%20incorp%20with%20chg%203.pdf . This lays out how Inspectors go through the process of approving an Airworthiness Certificate, including Experimental Amateur-Built.
 
 Also, FAR 23.1357 "Circuit protective devices" (d): "If the ability to reset a circuit breaker or replace a fuse is essential to safety in flight, that circuit breaker or fuse must be so located and identifed that it can be readily reset or replaced in flight."
 
  While Part 23 doesn't directly apply to Experimentals, if you followed the guidelines in 1357 I don't see how an Inspector or DAR could fault you.   -Bill Wade

They have to be accessible, but not necessarily in sight. The FAA guy who inspected my plane said I could have put them in my glove box if I wanted to. His comment is my sole source of info.

> Question for the group:  Are there any regs that state where circuit breakers can be located?  I have my hydraulic pump mounted on a bulkhead behind the co-pilot seat and would like to place the main hydraulic pump circuit breaker on the enclosure I've built around the pump. This breaker can easily be felt by the piot but is in a position that it shouldn't get bumped by things in the baggage area.  However, it isn't particularly visible.  Are there any regs that say that it must be visible - or is this something an inspector might find unacceptable later?
