Dear BP,We are in the process of researching an electrical upgrade for a 1950 apartment building with 8 one bedrooms and 2 studios, taking into account the following:We have no dishwashers or garbage disposals and won't install any,Stoves, ovens and heaters are gas,We are in Southern California,In one bedrooms: 10,000 BTU a/c for living room and 6,000 BTU for bedroom,Central water heater is gas,We'd like 2 electric vehicle chargers connected to house circuit (currently only has LED lights on it),We have no washers/dryers currently but might get one of each or a pair in the future,Our insurance company states each unit should have 150 amps.How many amps should we put in the main breaker?  

From Cali, work for a Tech/Energy company building a nationwide network of high speed EV chargers.

Make sure you get a security deposit and set expectations from the beginning (ie: landlords don't replace light bulbs, batteries, etc).

All the sensors and the keypad run of batteries and the base unit plugs in but has a battery backup.You would have four entry sensors for the four doors, at least one glassbreak sensor, and at least one motion sensor.

Examples: replacing burned out light bulbs, furnace filters, batteries in doorbells, etc.
