Water Heater wiring

I want to wire an electric water heater. There is a lockout bracket on the circuit breaker for this circuit in the main service panel.

What's the proper way to connect to the heater? Can I run 10-2 (30 amp circuit) to a junction box near the heater and then run a length of flexible conduit or seal-tight from the junction box to the water heater? If so, how long/short should this appliance whip be?

Does the breaker lockout allow me to dispense with the need for a disconnect within "line of sight" of the water heater?

Thanks in advance.

I'm not an electrician, but you're right, a 30 amp double-pole breaker with 10-2 wg is the way to go for an electric water heater.
Curve the appliance whip for extra length from the j-box to the heater in case you need the extra length for a different size water heater in the future.
Call your Building Inspection Department for local code on the breaker lockout.
Good Luck!
