We are doing some kitchen remodeling. We should finish laying tile Monday afternoon. We have appliances arriving sometime Wednesday. </p><p>Questions:</p><p>1- How long should we let the tile and thinset sit before grouting?</p><p>2 - How long should we let the grout dry? </p><p>3 - Can we move our appliances in before we do the grouting?
1 AC is created by generators in power plants, and other sources. 2  This AC current is delivered to our homes and businesses by the power lines we see everywhere. 3  The frequency of repetition of this current is 60 Hertz.
The VFDâs Carrier (Switching) frequency is the frequency of the PWM (Pulse Width Modulation) pulses, i.e. the frequency at which the VFDâs output transistors; usually IGBTs (Insulated Gate Bipolar Transistors), are switching. This typically ranges from 2 to 20 kHz.
