Electrical lines will hopefully be NMB (Non-Metallic Barrier) sheathing wiring. This will be from the battery bank to the circuit breaker, and then to the outlet, wall switch, or lamps. All light switches will be slider switches allowing the tenant to set the intensity of the light. GFI outlets will be in place anytime there is a water fixture one meter from the outlet. These are like standard outlets, but have arc protection to reduce the chance of electrocution.
Regular outlets will have two 3 prong sockets, and these outlets will also have 2 USB-C ports for charging without the need for a power brick. This in turn will make the outlet more functional and capable. GFI outlets will not be able to have this feature, but if you were to use both USB-C port, you can have up to 4 items able to be powered in one outlet.
