6.4.2 110 VAC Circuits
Refer to Figure 6-3 for numbered references in brackets in the following 110 VAC description.
Current for the 110 VAC Circuits is provided by the Dynamote Inverter located in the truck cab (see the
Dynamote Manual for details of the operation and construction of the Inverter). Output from the Inverter
goes to the 30 Amp Breaker (No. 2) in the Electrical Box (No. 1) and the 15 Amp Breaker (No. 4) in the
Electrical Box (No. 3), both mounted on the rear fire wall of the truck cab.
The 30 Amp Breaker (No. 2) controls the current to the 15 Amp Twist Lock Outlet (No. 8) located at the
tip of ladder Section 3. Cabling is from the Electrical Box (No. 1) to the Contact Rings in the Turntable
(No. 10), to a Junction Box (No. 11) located at the base of the ladder, to the weather proof Outlet Box
(Nos. 7, 8 and 9) at the tip of the ladder. The 30 AMP Breaker (No.2) is a Ground Fault Interceptor (GFI)
which activates at 5 mA.
6.4.3 110 VAC Ladder Cable Layout
The 110 VAC Cable must reach from the junction box at the base of the ladder to the outlet in Section 3 in
all attitudes of extension from 0’ to 85’. This is accomplished by means of the cable layout, illustrated in
Figure 6-5 "110 VAC Cable Layout-Ladder Extended". The circled numbers are the call-outs referred to in
the text.
6.4.4 Ladder Retracted
With the ladder retracted, the cable is in the position illustrated in Figure 6-4.
