grounds shall be used if required to attain a satisfactory level of system performance desired. For maximum system reliability, all serrated eyelets and screws or bolts utilized at points of ground shall be either coated or plated with an electrical conductive type material to improve their resistance to corrosion. 3.4.1.4. All electromagnetic type switches, relays and solenoids furnished shall be suppressed to protect the entire electrical system from major damage from the large negative voltage spikes these devices can produce. 3.4.1.5. All auxiliary electrical circuits shall be safety protected from current overloading by automatic resetting type heavy-duty automotive circuit breakers, each properly capacity sized to the circuit they serve. A master circuit breaker, minimum 150-amp shall also be furnished. 3.4.1.6. All terminals and connectors furnished shall be designed and approved by their manufacturer for heavy-duty automotive vocational application; material shall be a corrosion-resistant type. To eliminate disconnects; all terminals furnished shall incorporate a positive locking, seated type design to assure terminal position. Socket (female side of connectors) shall be wired to electrical source side of circuit and plug (male) side of connector shall be wired to electrical load side of the circuit to help prevent a short circuit when disconnected. All connections made on the vehicle underbody shall be adequately protected against moisture and corrosion with dielectric grease, heat shrink tubing, or other similar techniques. 3.4.1.7. All insulated cable furnished shall comply with SAE Standards J 1 127 and J1128. All wiring furnished in the engine compartment area, where extreme heat and fire are of concern, shall be multi-stranded, low voltage insulated automotive type cross-linked polyethylene fire-retardant SAE approved SXL type. All wiring furnished in the body portion of the coach shall be multi- stranded, low voltage insulated automotive type; either SAE approved SXL or GXL types are acceptable. All wiring in each circuit shall be of sufficient size, and with 125% capacity rating of anticipated load to transmit the electrical current load of the circuit. Sizing shall take into account the length of the circuit and the voltage drop occurring in the circuit. Voltage at the load shall be +/- 5% of rated voltage when measured in a normal operating state. 3.4.1.8. All wiring shall be routed meeting the following minimum requirements: 3.4.1.8.1. No contact with sharp or puncturing edges. 3.4.1.8.2. No tension or strain between fixed points. 3.4.1.8.3. Adequate and safe clearance of moving parts. 3.4.1.8.4. 5-inch clearance from radiant heat sources. 3.4.1.8.5. Adequately secured to prevent pinching. 3.4.1.8.6. Wiring to be color-coded and numbered, grease-, oil- and moisture- resistant and securely fastened. City of Pleasanton Outreach Vehicle Specifications(Version 1.1) Page 19 of 23
