I have a 2 part question. 1st what are some best methods to deliver generators 26kw abs below? 2nd What are some issues that could happen while installing load shedding modules to condenser units that could cause problems to unit. We turn off power to Condensor but had a coupe issues arise where condenser didn't operate after module was installed and home owner blames us for damage. One minute it works next minute it doesn't after install with no explanation
