Let's see who can figure this one out.

A 6 Volt (nominal) emergency lighting unit is being used for this. It is rated for a maximum load of 90 lamp Watts and will handle that load for a little over 90 minutes.

On the unit there are 2 lamp heads and each one has a 9 Watt rated sealed beam lamp in it.

I wish to add two remote lamp heads and each will have a 25 Watt lamp. The first one will be at a distance of 22 feet from the unit. The second one will be 15 feet from the first. What gauge wire should I can use to keep the Voltage drop to under 5.0% as per code requirements? Please answer this as a two part question. Unit to remote A and remote A to remote B.

For safety there is a 15 Amp fuse inside the unit for the attached lamp heads and at the terminals for remotes there's a second fuse of 20 Amps. To put this another way there are 2 fused circuits for loads.

Please remember this is a 6 Volt system and thus a 5% Voltage drop is 0.3 Volts.
