Don,
Yes, Anderson Powerpoles are fine connectors. Just don't use too many
of then when powering a 100 watt rig.
IMHO, Rigrunners are handy things, but running a 100 watt transceiver
from them is cause for significant voltage drops. Each contact point
will have some resistance. A fused Rigrunner has 6 contact points in
line with the power supply (you need to count those in both the negative
and positive lines)
If you have a K2/10, you can run it from the Rigrunner, but if a K2/100,
wire it direct to the power supply - there will be less voltage drop.
Save the Rigrunner for accessories and other lower current devices.
